      Description

      When I create an aria table the first time page_checksum is not listed in show table status when the table is created the first time. when alter is done later it is listed:

       
      create table t (id int) engine = aria;
       
      show create table t\G
      *************************** 1. row ***************************
             Table: t
      Create Table: CREATE TABLE `t` (
        `id` int(11) DEFAULT NULL
      ) ENGINE=Aria DEFAULT CHARSET=latin1 PAGE_CHECKSUM=1
       
      show table status like 't'\G
      *************************** 1. row ***************************
                  Name: t
                Engine: Aria
      ...
              Checksum: NULL
        Create_options: transactional=1
               Comment: 
       
      alter table t table_checksum=1;
       
       
      show create table t\G
      *************************** 1. row ***************************
             Table: t
      Create Table: CREATE TABLE `t` (
        `id` int(11) DEFAULT NULL
      ) ENGINE=Aria DEFAULT CHARSET=latin1 CHECKSUM=1 PAGE_CHECKSUM=1
       
      show table status like 't'\G
      *************************** 1. row ***************************
                  Name: t
                Engine: Aria
              Checksum: 0
        Create_options: checksum=1 page_checksum=1 transactional=1
       
      alter table t table_checksum=0;
      show create table t\G
      *************************** 1. row ***************************
             Table: t
      Create Table: CREATE TABLE `t` (
        `id` int(11) DEFAULT NULL
      ) ENGINE=Aria DEFAULT CHARSET=latin1 PAGE_CHECKSUM=1
       
      show table status like 't'\G
      *************************** 1. row ***************************
                  Name: t
                Engine: Aria
              Checksum: NULL
        Create_options: page_checksum=1 transactional=1
      

      This makes this information less reliable for monitoring for example...
