Given that those are coming from different backends, I don't think
they're related.  The NOTICE can be ignored in any case.

select * from pg_proc where oid = 59668709 ... but I bet you'll find
there's no matching entry.  This seems to indicate that you've dropped
a function entry that was still in use somewhere.

What queries are drawing the error messages?  (If you don't know, turn
on query logging to find out.)
