Re: Is there any way to listen to NOTIFY in php without polling?

Hi Misa

The main goal is to perform some inter-system communication in the
case some rows in one table are updated (very seldom event).

I found example 27-2 at
http://www.postgresql.org/docs/8.0/static/libpq-example.html , that
does exactly what I was looking for using low-level socket functions.
It seems to me this solution works without polling.

PS: Compared to the libpq and php interfaces, the jdbc driver does a
really good job providing a useable interface for listen/notify to the
developers. Thanks :)
