I started to review this again. I'm down to figuring out whether the
typecache changes make sense; in doing so I realized that the syscaches
weren't perfectly defined (I think leftovers from when there was a
pg_multirange catalog, earlier in development), so I fixed that.
0001 is mostly Paul's v10 patch, rebased to current master; no
conflicts, I had to make a couple of small other adjustments to catch up
with current times.
The other patches are fairly obvious; changes in 0004 are described in
its commit message.
I'll continue to try to think through the typecache aspects of this
patch.
