[Fwd: How to use LISTEN / NOTIFY in a Perl program]

It seems that my mail never arrive to the mailing list.

Hi,

I have spend some time to read the very interesting feature LISTEN /
NOTIFY. I have found a lot of documentation on how to use in psql but
nothing on how to use in Perl DBI program. I don't know if it works.
I'll be very happy if someone had used it in a Perl script  and send me
an example.

Best regards
Thierry Missimilly
