    Tested with parquet metadata cache. Currently if you do a count(*) on parquet table having
metadata cache, we get that count from cache. For rowcount in planning: if a stats table exists
we get the count from stats table, otherwise we get it from groupscan which in parquet case
gets it from the metadata cache if exists.
