Actually, there seem to be a couple of unresolved bug reports that look
like the same thing ...

http://archives.postgresql.org/pgsql-hackers/2006-01/msg00216.php
http://archives.postgresql.org/pgsql-bugs/2005-12/msg00130.php
http://archives.postgresql.org/pgsql-general/2005-10/msg00975.php

The spelling of the message has changed since 7.3, but the code behavior
is still fundamentally the same.
