I have suggested no such thing, and in fact believe that the sort of index structure you are proposing would be of very little use. What I've been hoping to look into is *in memory* bitmaps used as an interface between index scans and the subsequent heap lookups. See eg this thread: http://archives.postgresql.org/pgsql-hackers/2004-10/msg00439.php particularly http://archives.postgresql.org/pgsql-hackers/2004-10/msg00668.php regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
