Hi Colleen,

When you use specify a host parameter... Php will attempt to connect to 
your postgres server using TCP/IP...
if you are not running the postgres backend with the -i option, then these 
connections won't happen. When you don't
specify a host name then Php will use a local Unix socket.

Not sure about the persistant database connection stuff. What version of 
Php are you using?
The only thing I could say, is to try explicitly closing the persistent 
database connections in your Php code.
Maybe there is a bug in Php.

Hope this helps,

Keith.
