Hm, CI fails[0]
This is most likely the reason why `select
pgstattuple('test_hashidx');` was omitted in pgstattuple tests: we are
not guaranteed about the number of bucket_pages in the empty index.
Maybe we should populate base relation and check for only non-volatile
fields like live_items and version?
