While this fix should be correct but it blocks pushdown of same-collation, e.g.,: ```SQL -- a, b : UTF8_LCASE ; everything same collation ... t1.a = t2.b AND t1.a = 'x' -- no COLLATE override infer: t2.b = 'x' (all UTF8_LCASE) ``` I'm thinking about a second approach, probably a bit more complex though. -- This is an automated message from the Apache Git Service.
