I would.
Not to knock poolers but they are limited and not very efficient. Heck
the best one I have used is pgbouncer and it has problems too under
heavy load (due to libevent issues). It also doesn't support all of our
auth methods.
Apache solved this problem back when it was still called NSCA HTTPD. Why
aren't we preforking again?
