So I started revising my notes on what to change the catalog structure
to, and immediately came up with

pg_opfamily
OIDopfamid            access method OIDopfname            family nameopfnamespace        family namespaceopfowner
owner's OID
 

But "opfamid" is a really unfortunate name, because it looks way too
much like it's supposed to be the ID of the family itself, rather than
of the index AM it's associated with.

I'm thinking of changing it to "opfmethod", and similarly rename
pg_opclass.opcamid to opcmethod.  That might break a few bits of code
that needn't be broken, but on the whole this patch will whack the
opclass-related catalogs around enough that most code looking at them
will need fixes anyway.

Comments?
