Utilize Omnibus packages for Database nodes
With the inclusion of Patroni into Omnibus (gitlab-org&2588 (closed)), we once again have alignment on the stack between Omnibus and GitLab.com.
One of the reasons for switching all of our users over to Patroni, was to be on the same solution GitLab.com users. However if GitLab.com uses different packaged versions of Patroni/PG along with different scripting and settings, much of the dogfooding value is lost.
We should explore what it would take to shift our production databases over to be based on the Omnibus-packaged Patroni and PG.
