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 default PG 9.6.0
$ dokku postgres:create db9.4
# Our original DB using PG 9.5
$ dokku postgres:create db9.5
# Migrate it like this for example
$ POSTGRES_IMAGE_VERSION=9.5 dokku postgres:clone db9.4 db9.5
$ 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 db9.5 my_app
$ dokku postgres:link db9.6 my_app
# Then unlink the old one
$ dokku postgres:unlink db9.4 my_app
$ dokku postgres:unlink db9.5 my_app
# And last, destroy the old container
$ dokku postgres:destroy db9.4
$ dokku postgres:destroy db9.5
```
