My experience with long running backend queries is that IE gives up
after a while but Netscape hangs on a lot longer. I don't know if this
is still the case. It was a while while I worked out why it worked for
me but not my boss...

You need to work who is giving up, the client which causes PHP to give
up, or if PHP itself is giving up. PostgreSQL doesn't care overly much,
as long as you complete the transaction.

My suggestion would be to spawn the update into a seperate process and
send a "Processing, please wait" to the client. When the stuff is done,
set a flag and indicate to the client that processing is complete.

Hope this helps,
