It looks like index "pg_class_relname_nsp_index" (which is an index on
pg_class) is corrupted. But not sure why it reports the following error
message (which looks like a post-commit cleanup caused error):

DEBUG: AbortCurrentTransaction
PANIC: cannot abort transaction 14135438, it was already committed

No.

Yes. There is no apparent bad side effect of vacuum full except that it
would block other accesses on the target table. But since you do it per
day(guess you do it on a nightly schedule), so this should not be a
problem.

The base table pg_class should be ok(pg_class_oid_ind indicates both
have the same cardinality). Try to reindex pg_class as the superuser.
