of the entries used to be zero, which I think I had deliberately done in
the name of saving cycles during ANALYZE, but it was really a rather
foolish decision.  Some of the more complex views in information_schema
were getting really bad plans for lack of statistics on the columns they
were joining over.

I'm not forcing an initdb for this, but I think there will be one soon
anyway to repair some bugs in the information_schema views.

memory say 'out of shared memory'; some were doing that and some just
said 'out of memory'.  Also add a HINT about increasing max_locks_per_transaction
where relevant, per suggestion from Sean Chittenden.  (The former change
does not break the strings freeze; the latter does, but I think it's
worth doing anyway.)

Fix a few other issues in passing.

do its thing if transaction blockState is TBLOCK_DEFAULT, but in
reality it had better check the low-level transaction state is
TRANS_DEFAULT as well.  Formerly it was not possible to wait for the
client in a state where the first is true and the second is not ...
but now we can have such a state.  Minor cleanup in StartTransaction()
as well.

small because shared_buffers is hogging too much shmem space.  Per pghackers

avoid most cases of the 'tuple concurrently updated' problem that
Robert Creager recently complained about.  Also remove a bunch of dead
code in StoreCatalogInheritance() --- it was still computing the complete
list of direct and indirect inheritance ancestors, though that list has
not been needed since we got rid of the pg_ipl catalog.
