User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0
Build Identifier:

Suppose we have a table t1 with a column c2. Now, consider the query:

select count(c1) as c2 from (select count(*) AS c1, c2 from t1 group by c2) AS t2 group by c2;

This is a silly query but a valid one. Now, suppose we introduce the following typo:

select count(c1_) as c2 from (select count(*) AS c1, c2 from t1 group by c2) AS t2 group by c2;

this query has a typo - c1_ instead of c1. The error message we should be getting is:

SELECT: identifier 'c1_' unknown

but instead we get:

SELECT: cannot use non GROUP BY column 'c1_' in query results without an aggregate function

which suggests that c1_ is an actual column, which just can't be used as it is.

Reproducible: Always
