  # NOTE: By design, this setting prevents the PGDATABASE environment variable
  # from affecting test runs, so that we don't accidentally affect the
  # production database during testing. If you're not concerned about that and
  # would like to have environment variable overrides, you could instead use
  # something like:
  #
  #   database: "_env:PGDATABASE:MyBlog_test"
  database: myblog_test
