Subject: 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.
