pg_dumpall segmentation fault

Hi,

I use pgsql 7.3.2.

The pg_dumpall fails while dumping the user-defined functions. But, the
pg_dump does fine. I have checked the archives and found two things.

1. To enable statement log and analyze. I did it.
2. To apply patch provided by Mr.Tom in the below link:

http://archives.postgresql.org/pgsql-bugs/2003-05/msg00011.php

I did it, but the problem still exists.

FYI, i have attached the sql log and the actual error thrown by pg_dumpall
(with -v). If you require further information, i can provide.

TIA.
