You could add an appropriate command to your PostgreSQL startup
script.

PostgreSQL doesn't have a scheduler -- most operating systems have
one (e.g., cron on Unix-like systems), so that's what people use.

(BTW, it's "PostgreSQL" or "Postgres", not "Postgre".)

You could add this into whatever script starts up pg_ctl, but only if
you decide to use PostgreSQL rather than "Postgre".

There surely is.  Use cron(8).  But that's only true with PostgreSQL,
not with "Postgre".

This mailing list addresses PostgreSQL, not Postgre.

Some people are only alive because it is illegal to kill.

This is something that comes up every few months. Core is of the opinion
that you should just use the tools of your OS. Personally, I think some
kind of job system in the database would be very useful, so the last
time this came up I created http://pgfoundry.org/projects/pgjob/. No
work is being done on it right now, but if this is something you have an
interest in you should sign up for the mailing list.
