Thanks for the reply. :-)
I read the manual again and now I understand that it's the libpq client
library which requires polling a function to retrieve the notifications
received from the server. Is there no way to tell the library "please call me
when a notification arrives"?
P.S.: I'm accessing PostgreSQL from Python if this matters, any of the Python
modules for PostgreSQL access is ok for me instead of libpq.
TIA,
Sincerely,
