But we keep signals blocked almost all the time in the postmaster, so in reality no signal handler can interrupt anything except the select() wait call. People complain about that coding technique all the time, but no one has presented any reason to believe that it's broken. 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
