Doc about HAVING condition says:
Each column referenced in condition must unambiguously reference a grouping
colum
HAVING x> AVG(bar) unambiguously references to a grouping column x
Is this bug ? It is very tedious to repeat same column expression in a
multiple times: one time in column expression, and n times in having clause.
Are there plans to fix this?
