From 9caafda579f699b43fa4c89bf13a2331ef00611e Mon Sep 17 00:00:00 2001
From: Joe Conway <mail@joeconway.com>
Date: Wed, 2 Aug 2006 01:59:48 +0000
Subject: Add support for multi-row VALUES clauses as part of INSERT statements
 (e.g. "INSERT ... VALUES (...), (...), ...") and elsewhere as allowed by the
 spec. (e.g. similar to a FROM clause subselect). initdb required. Joe Conway
 and Tom Lane.
