Pipelines not creating my database

[Jason Novotny]

Hi,

        services:
          - postgres

definitions:
  services:
    postgres:
      image: postgres
      environment:
        POSTGRES_DB: 'foo'
        POSTGRES_USER: 'foo'
        POSTGRES_PASSWORD: 'foo'

I expected a database foo to be created for my unit tests, but it doesn't appear to be the case. Is there something more I can do? I also tried adding another script to do psql -c 'CREATE DATABASE foo;' but psql could not be found.
