 ```shell
-# create a postgres service named lolipop
+# usage
-dokku postgres:create lolipop
+dokku postgres:create <service> [--create-flags...]
+```
 
-# you can also specify the image and image
+flags:
-# version to use for the service
+
-# it *must* be compatible with the
+- `-c|--config-options "--args --go=here"`: extra arguments to pass to the container create command (default: `None`)
-# official postgres image
+- `-C|--custom-env "USER=alpha;HOST=beta"`: semi-colon delimited environment variables to start the service with
+- `-i|--image IMAGE`: the image name to start the service with
+- `-I|--image-version IMAGE_VERSION`: the image version to start the service with
+- `-m|--memory MEMORY`: container memory limit (default: unlimited)
+- `-p|--password PASSWORD`: override the user-level service password
+- `-r|--root-password PASSWORD`: override the root-level service password
+- `-s|--shm-size SHM_SIZE`: override shared memory size for postgres docker container
+
+Create a postgres service named lollipop:
+
+```shell
+dokku postgres:create lollipop
+```
+
+You can also specify the image and image version to use for the service. It *must* be compatible with the postgres image.
+
+```shell

-# since DATABASE_URL is already in use, another environment variable will be
-# generated automatically
-#
-#   DOKKU_POSTGRES_BLUE_URL=postgres://postgres:ANOTHER_PASSWORD@dokku-postgres-other_service:5432/other_service
-
-# you can then promote the new service to be the primary one
-# NOTE: this will restart your app
-dokku postgres:promote other_service playground
-
-# this will replace DATABASE_URL with the url from other_service and generate
-# another environment variable to hold the previous value if necessary.
-# you could end up with the following for example:
-#
-#   DATABASE_URL=postgres://postgres:ANOTHER_PASSWORD@dokku-postgres-other_service:5432/other_service
-#   DOKKU_POSTGRES_BLUE_URL=postgres://postgres:ANOTHER_PASSWORD@dokku-postgres-other_service:5432/other_service

-
-# you can also unlink a postgres service
-# NOTE: this will restart your app and unset related environment variables
-dokku postgres:unlink lolipop playground
-
-# you can tail logs for a particular service
-dokku postgres:logs lolipop
-dokku postgres:logs lolipop -t # to tail
-
-# you can dump the database
-dokku postgres:export lolipop > lolipop.dump
-
-# you can import a dump
-dokku postgres:import lolipop < database.dump
-
-# you can clone an existing database to a new one
-dokku postgres:clone lolipop new_database
-
-# finally, you can destroy the container
-dokku postgres:destroy lolipop
 ```
 
-## Changing database adapter
+It is possible to change the protocol for `DATABASE_URL` by setting the environment variable `POSTGRES_DATABASE_SCHEME` on the app. Doing so will after linking will cause the plugin to think the service is not linked, and we advise you to unlink before proceeding.
 
-It's possible to change the protocol for DATABASE_URL by setting
+```shell
-the environment variable POSTGRES_DATABASE_SCHEME on the app:
-
-```
 dokku config:set playground POSTGRES_DATABASE_SCHEME=postgres2
-dokku postgres:link lolipop playground
+dokku postgres:link lollipop playground
 ```
 
-Will cause DATABASE_URL to be set as
+This will cause `DATABASE_URL` to be set as:
-postgres2://postgres:SOME_PASSWORD@dokku-postgres-lolipop:5432/lolipop
 
-CAUTION: Changing POSTGRES_DATABASE_SCHEME after linking will cause dokku to
+```
-believe the postgres is not linked when attempting to use `dokku postgres:unlink`
+postgres2://lollipop:SOME_PASSWORD@dokku-postgres-lollipop:5432/lollipop
-or `dokku postgres:promote`.
+```
-You should be able to fix this by
 
-- Changing DATABASE_URL manually to the new value.
+### unlink the postgres service from the app
-
-OR
-
-- Set POSTGRES_DATABASE_SCHEME back to its original setting
-- Unlink the service
-- Change POSTGRES_DATABASE_SCHEME to the desired setting
-- Relink the service
-
-## upgrade/downgrade
-
-At the moment a database can’t be upgraded  (or downgraded) inplace. Instead a clone has to be made, like this:
 
 ```shell
-# Our original DB using PG 9.5
+# usage
-$ dokku postgres:create db9.5
+dokku postgres:unlink <service> <app>
-
-# Migrate it like this for example
-$ POSTGRES_IMAGE_VERSION=9.6 dokku postgres:clone db9.5 db9.6
-
-# If it was linked to an application, first link the new DB
-$ dokku postgres:link db9.6 my_app
-# Then unlink the old one
-$ dokku postgres:unlink db9.5 my_app
-
-# And last, destroy the old container
-$ dokku postgres:destroy db9.5
 ```
 
-## Configuration
+You can unlink a postgres service:
 
-If you wish to tune the postgres instances various .conf files, you can find them by using the postgres:info command.
+> NOTE: this will restart your app and unset related environment variables
 
 ```shell
-dokku postgres:info lolipop 
+dokku postgres:unlink lollipop playground
-# or
-dokku postgres:info lolipop --data-dir
 ```
 
-## Backups
+### Service Lifecycle
+
+The lifecycle of each service can be managed through the following commands:
+
+### connect to the service via the postgres connection tool
+
+```shell
+# usage
+dokku postgres:connect <service>
+```
+
+Connect to the service via the postgres connection tool:
+
+> NOTE: disconnecting from ssh while running this command may leave zombie processes due to moby/moby#9098
+
+```shell
+dokku postgres:connect lollipop
+```
+
+### enter or run a command in a running postgres service container
+
+```shell
+# usage
+dokku postgres:enter <service>
+```
+
+A bash prompt can be opened against a running service. Filesystem changes will not be saved to disk.
+
+> NOTE: disconnecting from ssh while running this command may leave zombie processes due to moby/moby#9098
+
+```shell

+```
+
+You may also run a command directly against the service. Filesystem changes will not be saved to disk.
+
+```shell
+dokku postgres:enter lollipop touch /tmp/test
+```
+
+### expose a postgres service on custom host:port if provided (random port on the 0.0.0.0 interface if otherwise unspecified)
+
+```shell
+# usage
+dokku postgres:expose <service> <ports...>
+```
+
+Expose the service on the service's normal ports, allowing access to it from the public interface (`0.0.0.0`):
+
+```shell
+dokku postgres:expose lollipop 5432
+```
+
+Expose the service on the service's normal ports, with the first on a specified ip adddress (127.0.0.1):
+
+```shell
+dokku postgres:expose lollipop 127.0.0.1:5432
+```
+
+### unexpose a previously exposed postgres service
+
+```shell
+# usage
+dokku postgres:unexpose <service>
+```
+
+Unexpose the service, removing access to it from the public interface (`0.0.0.0`):
+
+```shell
+dokku postgres:unexpose lollipop
+```
+
+### promote service <service> as DATABASE_URL in <app>
+
+```shell
+# usage
+dokku postgres:promote <service> <app>
+```
+
+If you have a postgres service linked to an app and try to link another postgres service another link environment variable will be generated automatically:
+
+```
+DOKKU_DATABASE_BLUE_URL=postgres://other_service:ANOTHER_PASSWORD@dokku-postgres-other-service:5432/other_service
+```
+
+You can promote the new service to be the primary one:

+- `-I|--image-version IMAGE_VERSION`: the image version to start the service with
+- `-R|--restart-apps "true"`: whether to force an app restart
+- `-s|--shm-size SHM_SIZE`: override shared memory size for postgres docker container
+
+You can upgrade an existing service to a new image or image-version:
+
+```shell
+dokku postgres:upgrade lollipop
+```
+
+Postgres does not handle upgrading data for major versions automatically (eg. 11 => 12). Upgrades should be done manually. Users are encouraged to upgrade to the latest minor release for their postgres version before performing a major upgrade.
+
+While there are many ways to upgrade a postgres database, for safety purposes, it is recommended that an upgrade is performed by exporting the data from an existing database and importing it into a new database. This also allows testing to ensure that applications interact with the database correctly after the upgrade, and can be used in a staging environment.
+
+The following is an example of how to upgrade a postgres database named `lollipop-11` from 11.13 to 12.8.
+
+```shell
+# stop any linked apps
+dokku ps:stop linked-app
+
+# export the database contents
+dokku postgres:export lollipop-11 > /tmp/lollipop-11.export
+
+# create a new database at the desired version
+dokku postgres:create lollipop-12 --image-version 12.8
+
+# import the export file
+dokku postgres:import lollipop-12 < /tmp/lollipop-11.export
+
+# run any sql tests against the new database to verify the import went smoothly
+
+# unlink the old database from your apps
+dokku postgres:unlink lollipop-11 linked-app
+
+# link the new database to your apps
+dokku postgres:link lollipop-12 linked-app
+
+# start the linked apps again
+dokku ps:start linked-app
+```
+
+### Service Automation
+
+Service scripting can be executed using the following commands:
+
+### list all postgres service links for a given app
+
+```shell
+# usage
+dokku postgres:app-links <app>
+```
+
+List all postgres services that are linked to the `playground` app.
+
+```shell
+dokku postgres:app-links playground
+```
+
+### create container <new-name> then copy data from <name> into <new-name>
+
+```shell
+# usage
+dokku postgres:clone <service> <new-service> [--clone-flags...]
+```
+
+flags:
+
+- `-c|--config-options "--args --go=here"`: extra arguments to pass to the container create command (default: `None`)
+- `-C|--custom-env "USER=alpha;HOST=beta"`: semi-colon delimited environment variables to start the service with
+- `-i|--image IMAGE`: the image name to start the service with
+- `-I|--image-version IMAGE_VERSION`: the image version to start the service with
+- `-m|--memory MEMORY`: container memory limit (default: unlimited)
+- `-p|--password PASSWORD`: override the user-level service password
+- `-r|--root-password PASSWORD`: override the root-level service password
+- `-s|--shm-size SHM_SIZE`: override shared memory size for postgres docker container
+
+You can clone an existing service to a new one:
+
+```shell
+dokku postgres:clone lollipop lollipop-2
+```
+
+### check if the postgres service exists
+
+```shell
+# usage
+dokku postgres:exists <service>
+```
+
+Here we check if the lollipop postgres service exists.
+
+```shell
+dokku postgres:exists lollipop
+```
+
+### check if the postgres service is linked to an app
+
+```shell
+# usage
+dokku postgres:linked <service> <app>
+```
+
+Here we check if the lollipop postgres service is linked to the `playground` app.
+
+```shell
+dokku postgres:linked lollipop playground
+```
+
+### list all apps linked to the postgres service
+
+```shell
+# usage
+dokku postgres:links <service>
+```
+
+List all apps linked to the `lollipop` postgres service.
+
+```shell
+dokku postgres:links lollipop
+```
+
+### Data Management
+
+The underlying service data can be imported and exported with the following commands:
+
+### import a dump into the postgres service database
+
+```shell
+# usage
+dokku postgres:import <service>
+```
+
+Import a datastore dump:
+
+```shell
+dokku postgres:import lollipop < data.dump
+```
+
+### export a dump of the postgres service database
+
+```shell
+# usage
+dokku postgres:export <service>
+```
+
+By default, datastore output is exported to stdout:
+
+```shell
+dokku postgres:export lollipop
+```
+
+You can redirect this output to a file:
+
+```shell
+dokku postgres:export lollipop > data.dump
+```
+
+Note that the export will result in a file containing the binary postgres export data. It can be converted to plain text using `pg_restore` as follows
+
+```shell
+pg_restore data.dump -f plain.sql
+```
+
+### Backups
 
 Datastore backups are supported via AWS S3 and S3 compatible services like [minio](https://github.com/minio/minio).
 
-You may skip the `backup-auth` step if your dokku install is running within EC2
+You may skip the `backup-auth` step if your dokku install is running within EC2 and has access to the bucket via an IAM profile. In that case, use the `--use-iam` option with the `backup` command.
-and has access to the bucket via an IAM profile. In that case, use the `--use-iam`
-option with the `backup` command.
 
 Backups can be performed using the backup commands:
 
-```
+### set up authentication for backups on the postgres service
-# setup s3 backup authentication
-dokku postgres:backup-auth lolipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY
-
-# remove s3 authentication
-dokku postgres:backup-deauth lolipop
-
-# backup the `lolipop` service to the `BUCKET_NAME` bucket on AWS
-dokku postgres:backup lolipop BUCKET_NAME
-
-# schedule a backup
-# CRON_SCHEDULE is a crontab expression, eg. "0 3 * * *" for each day at 3am
-dokku postgres:backup-schedule lolipop CRON_SCHEDULE BUCKET_NAME
-
-# cat the contents of the configured backup cronfile for the service
-dokku postgres:backup-schedule-cat lolipop
-
-# remove the scheduled backup from cron
-dokku postgres:backup-unschedule lolipop
-```
-
-Backup auth can also be set up for different regions, signature versions and endpoints (e.g. for minio):
- 
-```
-# setup s3 backup authentication with different region
-dokku postgres:backup-auth lolipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION
- 
-# setup s3 backup authentication with different signature version and endpoint
-dokku postgres:backup-auth lolipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION AWS_SIGNATURE_VERSION ENDPOINT_URL
- 
-# more specific example for minio auth
-dokku postgres:backup-auth lolipop MINIO_ACCESS_KEY_ID MINIO_SECRET_ACCESS_KEY us-east-1 s3v4 https://YOURMINIOSERVICE
-```
-
-## Importing Data
-
-The `import` command should be used with any non-plain-text files exported by `pg_dump`. To import a SQL file, use `connect` like this:
 
 ```shell
-dokku postgres:connect db < ./dump.sql
+# usage
+dokku postgres:backup-auth <service> <aws-access-key-id> <aws-secret-access-key> <aws-default-region> <aws-signature-version> <endpoint-url>
 ```
 
-## Security
+Setup s3 backup authentication:
 
-The connection to the database is done over SSL. A self-signed certificate is
+```shell
-automatically generated when creating the service.  It can be replaced by a
+dokku postgres:backup-auth lollipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY
-custom certificate by overwriting the `server.crt` and `server.key` files in
+```
-`/var/lib/dokku/services/postgres/<DB_NAME>/data`.
-The `server.key` must be chmoded to 600 and must be owned by the postgres user
-or root.
 
-## Disabling `docker pull` calls
+Setup s3 backup authentication with different region:
+
+```shell
+dokku postgres:backup-auth lollipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION
+```

+
+```shell
+dokku postgres:backup-auth lollipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION AWS_SIGNATURE_VERSION ENDPOINT_URL
+```
+
+More specific example for minio auth:

+Postgres does not handle upgrading data for major versions automatically (eg. 11 => 12). Upgrades should be done manually. Users are encouraged to upgrade to the latest minor release for their postgres version before performing a major upgrade.
+
+While there are many ways to upgrade a postgres database, for safety purposes, it is recommended that an upgrade is performed by exporting the data from an existing database and importing it into a new database. This also allows testing to ensure that applications interact with the database correctly after the upgrade, and can be used in a staging environment.
+
+The following is an example of how to upgrade a postgres database named `lollipop-11` from 11.13 to 12.8.
+
+```shell
+# stop any linked apps
+dokku ps:stop linked-app
+
+# export the database contents
+dokku postgres:export lollipop-11 > /tmp/lollipop-11.export
+
+# create a new database at the desired version
+dokku postgres:create lollipop-12 --image-version 12.8
+
+# import the export file
+dokku postgres:import lollipop-12 < /tmp/lollipop-11.export
+
+# run any sql tests against the new database to verify the import went smoothly
+
+# unlink the old database from your apps
+dokku postgres:unlink lollipop-11 linked-app
+
+# link the new database to your apps
+dokku postgres:link lollipop-12 linked-app
+
+# start the linked apps again
+dokku ps:start linked-app
+```
