From 9f76ea0a7096ddd3f27db1b0263e8207473320fe Mon Sep 17 00:00:00 2001
From: Marc Balmer <marc@msys.ch>
Date: Fri, 13 Feb 2015 10:49:11 +0100
Subject: [PATCH] - Hardcode the few OIDs that are used internally and
 rearrange some header files, so the server development files are no longer
 used. - Conditionally compile the setSingleRowMode() function, since it only
 exists for PostgreSQL 9.2+.
