Обсуждение: automatic verifications

Hi!

I am new with PostgreSQL and I want to know if this database give the
possibility  to verify automatically, each night, if some records are
too old (by example, if session_date is older than a month) and if so
delete them.

Thanks for your help!

That's not really something you would build into a server.  I'd do it
by writing a maintenance script and having it run by 'cron'.  The
script would just do a "DELETE FROM sessions WHERE session_date < ..."

The normal way to do that would be to run a daily cron job that deletes
all of the records with session date older than one month.
