Hi,
How many processes should the persistent connection start on the server. I would think one is the answer. However after just a few reloads of a page that calls pg_pconnect() and does ~20 queries and I have five idle procesess listening to the web server.
With pg_connect() and pg_close() there is similar behaviour as well.
php is version 4.1.1
postgresql is version 7.1.3
