Set postgres image/version with postgres:create option
I know you can choose a non-default postgres version like this:
POSTGRES_IMAGE_VERSION=9.4 dokku postgres:create <name> </name>
But I usually use the dokku shell through SSH, and I don't see a way to set the postgres version when running like this. I'd like to be able to do the following:
ssh dokku postgres:create <name> -v 9.4 </name>
or maybe this way, to also support different images:
ssh dokku postgres:create <name> -i postgres:9.4 </name>
Is there a way to do this already that I'm not seeing? Or would you be open to a PR to add this option?
