We've been using pconnect for exactly the same reason. Though startup
time for our dictionary is even higher (around 2 seconds). The problem
is that persistent connections in PHP are not clean implemented, they
can get randomly garbage collected. The problem seems well known, though
I'm unaware of any fix. I think it's best to use pgbouncer and plain
connect ATM. Additionally, as mentioned earlier, using pconnect under
the Apache webserver is not a good idea at all, at least not with it's
current architecture.
