@abrandl started a discussion: (+1 comment) @jprovaznik Theoretically, the tablesample approximate count strategy would fall back to exact counting if the table was deemed "small enough". In that sense, we could use it everywhere, so that we would get an approximate count if the table is big. However, I'm not yet sold on this really and would like to see the approximate counting strategy in action first.
