Hi All,
I ' m using the postgresql datbase to stores cookies. Theses cookies
become invalid after 30 mn and have to be deleted. i have defined a
procedure that will
delete all invalid cookies, but i don't know how to call it in loop way
(for example each hour).
I think that it possible because this behaivor is the same of the
autovaccum procedure that handle the vaccum process every time (60s in
default way).
After reading the documentation, it seems that triggers can't handle
this stuff .
how can i resolve the problem ?
Thanks

Use your system's crontab! (On Windows, "scheduled tasks" or whatever).

Time-based event scheduling is done using cron, external to the
database.
