From 30f609484d025bfb7c69f8f6b9610dc981cb5fb8 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Mon, 12 May 2003 23:08:52 +0000
Subject: Add binary I/O routines for a bunch more datatypes.  Still a few to
 go, but that was enough tedium for one day.  Along the way, move the few
 support routines for types xid and cid into a more logical place.
