Postgresql having trouble serving over 1000 connections

Hi There,

I am new to postgresql and we are thinking of migrating from MS-SQL to
postgresql, but I am having trouble getting postgresql to keep up with the
load.

I am using it to serve about 10000 images/hour (16/sec), so I am making that
many connections to determine which image to serve each time.

It seems to build up a lot of connections and then dissallow non-super
users. My sysadmin has set the connection limit to above 1000.

I am using php 4.3 on red hat 8 and postgresql 7.3.

I explicitly use pg_close at the end of my PHP scripts, but it doesn't seem
to have much impact.

Is there anything I should be doing in a high load situation. I have just
set up postgresql with default settings.

Thanks in advance,
Greg
