make sure the $Id tags are converted to $PostgreSQL as well ...

$Header: -> $PostgreSQL Changes ...

only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON.  Still TODO: provide some client-side autocommit
logic in libpq.

Create objects in public schema.

Make spacing/capitalization consistent.

Remove transaction block use for object creation.

Remove unneeded function GRANTs.

This is currently a cosmetic difference but I make the change now in case
the macros diverge one day.

with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

initdb/regression tests pass.

tests pass.

written a generic framework of rules that the contrib makefiles can
use instead of writing their own each time.  You only need to set a few
variables and off you go.

make it use Makefile.shlib, etc.

default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.

Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.

initdb forced.

PG_RETURN_BOOL(0) instead of return 0.

in c.h we should be using the visible structure.  We should only see
de-TOASTed values in this program.  The old method refused to compile
because the length macro was no longer an lvalue.
