Hi PostgreSQL hackers!

A while ago we received the bug report below against pg_autovacuum.
Since it runs as a daemon, it should detach from its controlling
terminal by executing sth like

        int nullfd = open("/dev/null", O_RDWR);
        dup2(nullfd, 0);
        dup2(nullfd, 1);
        dup2(nullfd, 2);
        if (nullfd != 0 && nullfd != 1 && nullfd != 2)
                close(nullfd);

(taken from syslog-ng which does it properly).

Can you do that in the next release?

Thanks in advance and have a nice day!

Martin

Package: postgresql
Version: 7.4.1-1

When /etc/init.d/postgresql is run, pg_autovacuum maintains connections
to the startup tty on fds 0, 1 and 2.  When run from the console (as part
of (apt-get upgrade), this caused some hiccups to a following getty.

In any case, it's considered bad behaviour on the part of a long-running
daemon.

(If you feel this is pg_autovacuum's fault rather than the init script's,
please reassign to postgresql-contrib.)

Thanks!
