From 449a00fbbd49c00ba031432e8b6913a55e8ad1f6 Mon Sep 17 00:00:00 2001

Subject: Fix the raw-parsetree representation of star (as in SELECT * FROM or
 SELECT foo.*) so that it cannot be confused with a quoted identifier "*".
 Instead create a separate node type A_Star to represent this notation. Per
 pgsql-hackers discussion of 2007-Sep-27.
