Postgres FD Implementation

Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in 

pgsql-hackers.  pg_opclass now has a row for each opclass supported by each
index AM, not a row for each opclass name.  This allows pg_opclass to show
directly whether an AM supports an opclass, and furthermore makes it possible
to store additional information about an opclass that might be AM-dependent.
pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we
previously expected the user to remember to provide in CREATE INDEX commands.
Lossiness is no longer an index-level property, but is associated with the
use of a particular operator in a particular index opclass.

Along the way, IndexSupportInitialize now uses the syscaches to retrieve
pg_amop and pg_amproc entries.  I find this reduces backend launch time by
about ten percent, at the cost of a couple more special cases in catcache.c's
IndexScanOK.

Initial work by Oleg Bartunov and Teodor Sigaev, further hacking by Tom Lane.

initdb forced.

This is an implementation of RD-tree data structure using GiST interface
of PostgreSQL. It has built-in lossy compression - must be declared
in index creation - with (islossy). Current implementation provides index
support for one-dimensional array of int4's - gist__int_ops, suitable for
small and medium size of arrays (used on default), and gist__intbig_ops for
indexing large arrays (we use superimposed signature with length of 4096
bits to represent sets).

* pg_amproc.h
* definition of the system "amproc" relation (pg_amproc)
* along with the relation's initial contents. The amproc
* catalog is used to store procedures used by index access
* methods that aren't associated with operators.
* along with the relation's initial contents.
*
* The amproc table identifies support procedures associated with index
* opclasses. These procedures can't be listed in pg_amop since they are
* not associated with indexable operators for the opclass.
*
* Note: the primary key for this table is <amopclaid, amprocnum>.
