You broke a system catalog index. Without seeing what you changed and
where, it's impossible to say just how, but that's the bottom line.

In recent versions of PG, opclass 10032 is btree name_ops (unless you've
also added/removed system catalog entries), which is a pretty plausible
thing to be one of the first indexscanned fetches during relcache.c
initialization, so I don't think there's any great significance in this
particular error message. It's likely that you broke *all* indexscans
not just one specific one.
