Subject: [PATCH] Submitted by Openlink, requires -DOPENLINK_PATCHES in
 Makefile.global

varchar.diff
------------
This patch was necessary for the OpenLink Postgres Database Agent.
I think this fixes a bug anyway.

The following query demonstrates this bug:

  create table foo (bar varchar);
  insert into foo values ('');          -- no problem
  select * from foo where bar = '';     -- fails
