The other major issue with the Bitmap index patch as it stood in 2007 was that performance just wasn't that much faster than a btree, except for specific corner cases. Otherwise, someone else would have been interested enough to pick it up and finish it. So performance testing of the patch is absolutely essential. -- --Josh Josh Berkus PostgreSQL San Francisco -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
