Noah Misch d0a049987e Avoid ERROR at ON COMMIT DELETE ROWS after relhassubclass=f. 
Commit 7102070329 fixed a similar bug, but
it missed the case of database-wide ANALYZE ("use_own_xacts" mode).
Commit a07e03fd8f changed consequences
from silent discard of a pg_class stats (relpages et al.) update to
ERROR "tuple to be updated was already modified".  Losing a relpages
update of an ON COMMIT DELETE ROWS table was negligible, but a
COMMIT-time error isn't negligible.  Back-patch to v13 (all supported
versions).
