Обсуждение: pg_hba.conf reload

is there any way in postgres (7.1.3) to get postgres to source the
pg_hba.conf file without restarting the database completely?

will any new backend use a modified pg_hba.conf if it is modified while
postgres is running?

In 7.1.X and earlier, pg_hba.conf is reread on every connection request.
7.2.X will requires a sighup to the postmaster to reload pg_hba.conf.
