Replaces
CALL expr . expr
toCALL expr_var . expr_func_norm
. There was a if-block before that checked if the firstexpr
is a ColumnRef and the secondexpr
is a FuncCall node. That check is not need now since expr_var and expr_func_norm are reduced to ColumnRef and FuncCall node respectively.This change also prevents shift\reduce ambiguity with CALL subquery syntax.
