Are you absolutley sure you close postgres connection within your PHP
pages? I've experienced very same problem using PHP (i was not using
persistent database connections - those seemed much slower) because I
was missing several 'pg_close()' instructions.

The same thing happened to my developers here, using java/tomcat/jdbc to
connect to postgres. Make sure you close all your postgres connections.
