      Description

      Currently mysql_upgrade stores version info in file $datadir/mysql_upgrade_info

      This has a set of disadvantages:

      • information is not accessible from the SQL level
      • when restoring a backup from an older server version the file information will not match the actual database version state
      • mysql_upgrade can only be executed successfully by an OS user with write access to the datadir
      • mysql_upgrade can perfectly perform its upgrade tasks while running remotely on a different host, but will write the version info file locally then

      All of these points would be solved if upgrade version information would be stored in a system table instead of a local file ...
