Is pgbouncer enabled by default in here ?
One other request - could you write how to use it (connect to it) ?
Not really replying to your question.
But recently I got the occasion to work with https://github.com/CrunchyData/postgres-operator .
It's a bit rough around the edges wit the v5, which is very recent, but overall I was really happy with it.
I am still not using it in production but it's on the way.
I'm curious if you've looked at https://github.com/zalando/postgres-operator and had thoughts on how it compared. The CrunchyData operator seems to use Patroni and links to the Patroni documentation which links to the Zalando Postgres Operator from the same company as Patroni.
