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.
