Hi, trying to reproduce a performance problem I just found:
=# CREATE TABLE twocol(col01 int, col02 int); =# SELECT DISTINCT col01, col02, col01 FROM twocol ; ERROR: XX000: ORDER/GROUP BY expression not found in targetlist LOCATION: get_sortgroupref_tle, tlist.c:341 which appears to be a 9.6 regression, presumable fallout from the path restructuring.
