Indeed the transparent proxy use case is where replication through
pgbouncer makes sense. There's quite some reasons to set up PgBouncer
like such a proxy apart from security policies. Some others that come
to mind are:
- load balancer layer of pgbouncers
- transparent failovers
- transparent database moves

And in all of those cases its nice for a user to use a single
connection string/hostname. Instead of having to think: Oh yeah, for
backups, I need to use this other one.
