Обсуждение: pg_dump segfaults on command-line arguments?

This seems like such a silly thing I'm sure it's been fixed already. It
happens on both machines where I have 7.2.1 installed. It appears to
segfault when receiving any long options it doesn't recognise. Is it a
problem with my libraries or with postgres? OS is Debian 2.2.

Feel free to tell me it's because the system needs an upgrade :)

Yeah, it has, but there's been no 7.2.2 release.  You could get the
7.2-branch patch from the CVS archives:

2002-05-13 22:08  ishii

    * src/bin/: pg_dump/pg_dump.c, psql/startup.c (REL7_2_STABLE): Fix
    bug in pg_dump and psql (to reproduce the bug, just try pg_dump
    --nonexistingoption).

    per report from sugita@sra.co.jp on Thu, 09 May 2002 11:57:51 +0900
    (JST) at pgsql-patches list.

    Illegal long options to pg_dump makes core on some systems, since
    it lacks the last null sentinel of struct option array.

    Attached is a patch made by Mr. Ishida Akio <iakio@pjam.jpweb.net>.
