There was a patch to do this posted recently here as well. http://archives.postgresql.org/pgsql-patches/2008-03/msg00335.php Hm. I suppose it's true that you could make Datum 64-bit even on 32-bit machines and make int8 and float8 pass-by-value. Seems unlikely to be a net win though. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's On-Demand Production Tuning -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches
