In particular, no more compiled-in default for PGDATA or LIBDIR. Commands
that need them need either invocation options or environment variables.
PGPORT default is hardcoded as 5432, but overrideable with options or
environment variables.
Changes:
* Unique index capability works using the syntax 'create unique
index'.
* Duplicate OID's in the system tables are removed. I put
little scripts called 'duplicate_oids' and 'find_oid' in
include/catalog that help to find and remove duplicate OID's.
I also moved 'unused_oids' from backend/catalog to
include/catalog, since it has to be in the same directory
as the include files in order to work.
* The backend tries converting the name of a function or aggregate
to all lowercase if the original name given doesn't work (mostly
for compatibility with ODBC).
* You can 'SELECT NULL' to your heart's content.
* I put my _bt_updateitem fix in instead, which uses
_bt_insertonpg so that even if the new key is so big that
the page has to be split, everything still works.
* All literal references to system catalog OID's have been
replaced with references to define'd constants from the catalog
header files.
* I added a couple of node copy functions. I think this was a
preliminary attempt to get rules to work.
>From the create_aggregate man page...
"The arguments to state-transition-function-1 must be
(stype1,basetype), and its return value must be stype1."
create aggregate MIN (sfunc1 = int2smaller,
basetype = int2,
stype1 = int2);
will fail becase int2smaller and int2larger are in pg_proc
as returning an int4. Can't happen since both args have to
be int2.

I'm able to get through a 'make' of the backend with no errors except
the occasional 'might not be initialized error', which is nothing major,
just annoying.
Have a few patches from D'Arcy to incorporate, but am waiting until I can
get a clean compile first, which I'm hoping to have before bed, or sometime
tomorrow.
Note. all include files that have been hit so far have had extraneous
include files cleaned out and are reduced to...the lowest common
"include file", based on 'cc -Wall -I. test.c', where test.c is:
#include "postgres.h"
#include "<top of branches>" (ie. top of branches this time was utils/fcache2.h)
