Or even worse, the mount happens after PG starts (and creates directories on the root volume, not knowing they should go onto the mount instead). I'm too lazy to search the archives right now, but there was some case years ago where somebody destroyed their database via an ill-thought-out combination of automatic-initdb-if-$PGDATA-isn't-there and slow mounting. We'd have to be very sure that any auto-directory-creation behavior didn't have a potential for that. Perhaps doing it only for temp tablespaces alleviates some of the risk, but it still seems pretty scary. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
