That's a bit different than the gc_count presented in 0004, because
there is no relationship to autovacuum with the cleanup of the
entries, still there is some overlap in the thought process: this
suggestion just makes sure that any backend holding local references
to a shared entry with a different age does not attempt to manipulate
it after switching locally to a dropped state.
