Noah Misch f88cdb36c4 Lock owned sequences during ALTER TABLE SET { LOGGED | UNLOGGED }.
These commands already make the persistence of owned sequences follow
owned table persistence changes.  They didn't lock those sequences.
They lost the effect of nextval() calls that other sessions make after
the ALTER TABLE command, before the ALTER TABLE transaction commits.
Fix by acquiring the same lock that ALTER SEQUENCE SET { LOGGED |
UNLOGGED } acquires.  This might cause more deadlocks.  Back-patch to
v15, where commit 344d62fb9a978a72cf8347f0369b9ee643fd0b31 introduced
unlogged sequences.
