From e7889b83b7059e776f0a3d76bbbdd98687f4592c Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Mon, 3 Sep 2007 18:46:30 +0000
Subject: Support SET FROM CURRENT in CREATE/ALTER FUNCTION, ALTER DATABASE,
 ALTER ROLE. (Actually, it works as a plain statement too, but I didn't
 document that because it seems a bit useless.)  Unify VariableResetStmt with
 VariableSetStmt, and clean up some ancient cruft in the representation of
 same.
