1: Make sure you're not using pg_pconnect, but this doesn't sound like
that's the problem. Just making sure.
2: It sounds like php may be crashing at some point it its execution. Do
you have a log of its output when it's running? I've seen issues where if
you compile apache against one set of libs and php against another, then
apache/php starts having children crash and doesn't close the connections.
It takes a certain amount of time for the timeout to hit on the TCP/IP
layer and for the pg backend to close.
Are you sure you're actually closing down postgresql all the way when you
say you tried restarting the postgresql server? It could be that it's not
shutting all the way down. What does 'ps ax|grep post' say?
