The only reason why I did not propose that for ShmemAlloc is because of extensions potentially using this routine and having some special handling when it returns NULL. And changing it to behave like palloc would break such extensions. -- Michael -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
