I run PHP4 and IMP (http://www.horde.org) and we've gotten then to remove
the useof pg_pconnect() since it is broken. Broken how, you might
ask? Well, I ran on a standalone machine, no other web users but myself,
to test, and each tim eI hit the database with IMP,. it opened a new
backend, but it never reused old, idle ones ... eventually, you run out of
the ability to connect since you've locked up all connections ...
