Hello,
I wonder whether there is a "standard" "built-in" mechanism for a PostgreSQL
client to register with the database for notification in case of
modifications to a given table.
As I understand from the manual, the LISTEN and NOTIFY SQL commands require
to poll the database to retrieve the notification events...?
Would a trigger implemented in PL/Python allow to implement such a
notification mechanism? Would this be an efficient way to do so?
TIA,
Sincerely,
Wolfgang Keller
