with persistent connection on, i notice that with a web page load, it starts a new postgresql backend and detaches from it. therefore, the postgresql backend becomes stale and just hangs there for hours and days.

upon reloading the page, a new pgsql backend starts. within a minute, all the pgsql connection is maxed out, because all the processes become stale and were never released. this is from just me pressing reload 15 or so times. no one else have access to this server.

if i do 'apachectl stop' then 'apachectl start' again, the stale pgsql processes do get freed up. i didn't compile pgql with php as a loadable module. though it's using pgsql's dynamic library:

also note that the regular pgsql clients do release the backend postmaster right away after it quits.

there is a bug related to this one which showed similar symptoms: bug id# 8769
