If I have this query right in my head, this means that the average tuple in the property relation is taking up 19k? and the average tuple in the result_entry_pkey index is take 1.5k?!
Is there a way I can get the database to coalesce free space? A vacuum verbose shows that I have enough entries in the free space map...
