Review Comment:
Min/Max filters depend on column statistics, but push-down bloom filters can
support row-level filtering on the pax table without relying on column
statistics. Row-level filtering via bloom filters will be implemented later.
Furthermore, we should consider enabling statistics updates for the PAX
table in a bgworker. Currently, minmax_columns needs to be specified when
creating a table, and it will slow down the performance of data insertion.
