Test Omnibus GitLab with external PostgreSQL 12
Summary
PostgreSQL 12 will not be added to the Omnibus package or Helm install until GitLab 13.3. However, for customers wanting to run GitLab with an external PostgreSQL 12 database, we should know whether it works. For example, RedHat Collections skipped PostgreSQL 11 so we should know what options exist for customers using that software.
Proposal
Manually run the Omnibus package with an external PostgreSQL 12 database to validate that the application works in that configuration.
Out of scope
- Testing with GitLab-provided HA is out of scope for this issue. For replication and failover, GitLab uses a version of repmgr that doesn't work with PostgreSQL 12.
