Hm, I reviewed the discussion and actually I'm wrong: I came up with the unkillable process argument on my own. MauMau's problem was a deadlocked process because of trying to malloc() on its way out. I still think that unkillable processes are an issue, but perhaps it's sane to have postmaster wait for some time instead of just going away immediately. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
