commit    7a58167ea23c4ce3eb380e2b05fc33a8d08d44d1
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Thu Jun 25 23:07:15 2009 +0000
First released in: 8.4.0

    Add __attribute__((format_arg(1))) to the declaration of err_gettext(),
    to restore gcc's ability to crosscheck format arguments within elog.c.
    Noted in a test compilation with -Wformat-nonliteral enabled.
