Hello,
I have a connection leak problem when connecting to PGsql.
The connection just hang around and does not close. I have 
tryied to stress the server by doing *a lot* of persistent 
connections in a header(redirect) loop, and the pool 
worked ok with the stress. After a night of some 
connections, it grew to the maximum. (I use the PHAkt 
module for Ultradev PHP development)

I have tried to limit the maximum Pconnection number, but 
it is not working

I have built PHP like this.

'--with-config-file-path=/etc' '--disable-debug'
