It's fairly common with certain kinds of apps, including Rails and PHP.This is one of the reasons why we've discussed
havinga kind of
stripped-down version of pgbouncer built into Postgres as a connection
manager. If it weren't valuable to be able to relocate pgbouncer to
other hosts, I'd still say that was a good idea.
Ivan would really strongly benefit from running pgbouncer on his
appservers instead of connecting directly to Postgres.
