     We have several sql "select ... from ... where  ..." ,from pg_stat_statements, we found the select sql has many shared_blks_dirtied, shared_blks_written. is it by  "hint bits" updates ?  when checkpoint just completed, we saw many wal_fpi , wal_bytes with this select sql too.
     
  Thanks,

James
