From f9e4f611a18f64fd9106a72ec9af9e2220075780 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Sun, 12 May 2002 20:10:05 +0000
Subject: First pass at set-returning-functions in FROM, by Joe Conway with
 some kibitzing from Tom Lane.  Not everything works yet, and there's no
 documentation or regression test, but let's commit this so Joe doesn't need
 to cope with tracking changes in so many files ...
