Maybe I'm totally confused, but ... Couldn't normal backends call PostmasterIsAlive and exit if not, just like the startup process, the stats collector, autovacuum, bgwriter, walwriter, walreceiver, walsender and the wal archiver already do? I assumed they do, but now that I grepped the code it seems they don't. best regards, Florian Pflug -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
