Ugh.

That was your only chance of an easy way out :-(. At this point you
clearly have data corruption in one or more system catalogs, and there's
no particular reason to think that the damage is only in the catalogs
and not also in your user-data tables.
If the data is worth a substantial amount of money to you, I'd recommend
hiring a professional Postgres support company with experience in data
recovery. You can find some links here:

Otherwise, restore from your latest backup, and resolve to get better
at keeping backups, and ask some hard questions about the reliability
of the storage stack you're sitting on.
