The only barrier reason why elevel if needed is because of pg_wal in
SyncDataDirectory() that cannot fail hard. I don't have a great idea
here, except using a bits32 with some bitwise flags to control the
behavior of the routine, aka something close to a MISSING_OK and a
FAIL_HARD_ON_ERROR. This pattern exists already in some of the
*Extended() routines.
