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 ...

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

more robust way, by using COPY FROM filename instead of COPY FROM STDIN;
per a suggestion from Peter.

when the pg_class.relhassubclass value is already correct.  This should
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.
