Re: Preventing access temporarily.

I found something else on the web.

update pg_database set datallowconn = false where datname = 'foo';
update pg_database set datallowconn = true where datname = 'foo';

Seems to have worked OK.

Thanks for the pg_hab.conf suggestion. I'll add that to my notes.

Edit pg_hba.conf to reject all connections and reload. current
connections will stay connected, new ones will be refused. use
pg_stat_activity to monitor connections til they're all gone / idle.
