Thanks! I tried out your changes, and it's made some improvement. The query I originally submitted does seem to use the correct index.
However, if you just slightly modify the test query (which I see you made a unit test for), the same issue comes back up. Try making another unit test, checking that the below query uses 'tbl_b_idx', and the test case will fail: EXPLAIN ANALYZE SELECT MAX(b.id) as id FROM tbl_b b GROUP BY b.tbl_a_id; On Sunday, December 20, 2015 at 9:19:06 AM UTC-5, Noel Grandin wrote: > > I have committed a fix for this to master.
