If I understand you're suggestion, queries of the form SELECT * FROM rel WHERE ARRAY[ 1,2,3,4 ] <= x AND x <=ARRAY[ 1, 2, 3, 1000]; would no longer use an index. Is that correct? Are you suggesting removing MCV's in lieu of MCE's as well? -Nathan -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
