What is the bug?

I'm experimenting with the 8.5.2 chart version and when I'm installing with Pgbouncer feature disabled, everything works as usual but activating Pgbouncer flag on values.yaml, I get an error on the airflow-pgbouncer pod liveness probe:

Liveness probe failed: psql: error: ERROR: password authentication failed for user "[USERNAME]"

I'm using Azure for Postgres, and the username has an @ in the middle of the value but the log only shows the value before the @. I'm guessing this is why the auth is failing.

This is a continuation of issue #394

What version of the chart are you using?:

I am using version 8.5.2

I'm using the default Pgbouncer config from the repo with the following change:
