Oh dear :-( ... it seems that when you quote an identifier, the system
forgets to make sure that it's truncated to no more than 31 characters.
You've got a corrupted pg_class entry now for that index.

Dropping the table that the index is on should work. Hopefully
restoring just the one table is better than restoring your whole DB.
In the meantime, this is a high-priority bug fix...
