The patch as-submitted was a killer for the concept, because it automatically discarded information and there was no way to prevent that. To be acceptable, a GIT patch would have to be optional and it would have to expose in the catalogs whether a given index was lossy in this way or not (so that the planner could know whether a plan based on returning index keys would work). regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
