And another small patch set extracted from the bigger one, to keep 
things moving along:

0001: Add get_opfamily_method() in lsyscache.c, from your patch set.

0002: Add get_opfamily_member_for_cmptype().  This was called 
get_opmethod_member() in your patch set, but I think that name wasn't 
quite right.  I also removed the opmethod argument, which was rarely 
used and is somewhat redundant.

0003 and 0004 are enabling non-btree unique indexes for partition keys 
and materialized views.  These were v21-0011 and v21-0012, except that 
I'm combining the switch from strategies to compare types (which was in 
v21-0006 or so) with the removal of the btree requirements.
