For the most part, prepared queries and cursors give you a greater advantage due to their versatility -- both of which we do have. In the cases where an actual cache is useful, the client application could do it just as easily or temp tables can be used. I suspect it would be implemented more as a caching proxy than as an actual part of PostgreSQL, should someone really want this feature. --=-duA7am3AW1kVGadB3EuP Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQA/jD1K6DETLow6vwwRAoGgAKCECzHB9z/hSuhN8VgiDlJR+EfWNQCdHq6b 9bwfEQ6iaf2AP6ghESSl28M= =wXK6 -----END PGP SIGNATURE----- --=-duA7am3AW1kVGadB3EuP--
