Issue the vacuum against the owning table instead.  (If you're not sure
which that is, joining pg_class.reltoastrelid to pg_class.oid will

In general it sounds like you need to crank up the aggressiveness of
autovacuum, and perhaps look at whether your application is doing
useless updates on very wide fields.
