ok. What I find disturbing in the first sentence is the "but" conjunction: "... that clause is given but an index scan is chosen ..." Shouldn't it rater be "and"? When I read "but", I usually expect a contradiction. However I see no contradiction between specifying the USING INDEX clause and choosing index scan. -- Antonin Houska Web: https://www.cybertec-postgresql.com
