[ reads man pages for awhile... ] It looks to me like SIGIO is sent whenever the socket comes ready for either reading or writing, which makes it pretty nearly useless for detecting a broken-connection condition. You'd be too busy filtering out uninteresting signals --- and the signal handler itself can't do very much of that work. 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
