Use postgres noowner during ci:migrate

During ci:migrate, script outputs errors like Error: role does not exist.

This error is created because postgres is trying to change the owner during some of the executed commands. Error is not creating a problem during migration but it could confuse users so it should be silenced.

This is gitlab-ci related error.

Fixed in CI master by gitlab-org/gitlab-ci!252

@ayufan is this in CI 8-0-stable yet?

Status changed to closed

Yes, it's.
