Pconnects are absolutely necessary if we use tsearch2, because it initializes its dictionaries on a first query in a session. It's a very heavy process (500 ms and more). So, if we do not use pconnect, we waste about 500 ms on each DB connection. Too much pain.
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.
