So this is smelling like a kernel or filesystem bug. I wonder exactly which OS X update you're running, and what sort of filesystem the database is stored on. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
