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
