src/backend/parser: parse_agg.c
Log message:
Fix oversight in check_ungrouped_columns optimization that avoids
unnecessary checks for complex grouping expressions: we cannot check
whether the expressions are simple Vars until after we apply
flatten_join_alias_vars, because in the case of FULL JOIN that routine
can introduce non-Var expressions. Per example from Joel Knight.

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
