Обсуждение: executing a procedure with delay

I'd like to execute a stored procedure in postgresql one minute after a
table has been modified. In case there are two changes in less than one
minute, I want to reset the time that has to be waited before running
the procedure.

I think I need to use a trigger, but I don't know how...

Can you help me please?

Hello

you can use pg_sleep function. But using it in trigger is ugly,
because transaction stay in open state. Look to orafce on intersession
communication. Maybe you can use it.

other solution (vaguely): LISTEN/NOFIFY and an external prozess.
