Hmmm... You're right. How much longer does a '-m fast' take. The
reason I ask is because during a server shutdown, init doesn't wait
around long after the script exits. The problem with not using the '-m'
is that pg_ctl returns quickly but the DB may not be down, causing the
system to pull the rug out from under it.
Cheers!
