I think you are in luck: this looks like the corrupted data is in one of the indexes on pg_class, so you should be able
torecover by reindexing.
See the man page for REINDEX for the gory details of doing this (you need the "ignore system indexes" option, and maybe
someother pushups depending on your Postgres version).
