Maybe good would be to add Redis. @markpundsack what do you think about current PostgreSQL integration?

added Stretch in GitLab FOSS label

@ayufan Current Postgres integration has been very brittle at best. :) But it's directionally correct.

changed milestone to %10.2

removed Stretch in GitLab FOSS label

@bikebilly At this point, we know it's not happening for 10.0. I'm tentatively marking it for 10.2 so there's time to get some feedback about Auto DevOps before committing further, and to give us breathing room to work on GKE.

@markpundsack can we start with PostgreSQL and Redis? I know that MySQL and Mongo are popular but I think we should focus on growing technologies.
