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. Regards, Clemens 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.
