I am not entirely clear what you are trying to do, but in general using a
web browser, there is no way to have a persistent, bi-directional
communication to an HTTP server. At least not one that you can control.

There are ways to accomplish this kind of thing using JavaScript and
iframes. So as as far as PHP and Postgres is concerned, the answer to your
question is, "No, but it can be done."
