Ah, I hadn't considered that, query time dominates all my scripts.

Another thing I've noticed. Just for the record ... Persistent connections
do appear to go away after time. When I used them on my relatively idle
(compared to many) server, there almost always were none early in the
morning. With non-scientific methods, and random observations I determined
that the time period was probably between one hour and one day.

Too bad all this info about factors affecting pg_pconnect weren't all in
one place...
