Problem with PG gem

[siba2893]

If trying to create a rails app from scratch using the --database=postgresql flag it will run into an error where the pg gem wont install because it lacks of a psql installation.

For anyone interested in using other databases / javascript options from the beginning in a Dockerized Rails app, I wrote a bash script which should do the trick. It uses dockerfile-rails to generate a compose file, which it then copies and edits to provide the dev enviroment.
