This error is likely the result of using a temp table without EXECUTE or
having one of your tables dropped (recreating it won't help). plpgsql
caches query plans, but doesn't track the plans dependencies, so if any of
the underlying objects change you can get this error.

The plans are cached once per backend, the connection pool keeps that same
backend open forever which means you can never safely change your
schema without restarting the pool.

SELECT relname FROM pg_class WHERE oid = 215106760;
