Replace mysql_version check with frm_version for virtual columns inside InnoDB

Details

    Description

      • Start 10.1 server, all defaults are sufficient;
      • create a table as 

        CREATE TABLE t1 (f1 INT, f2 INT AS (f1) VIRTUAL) ENGINE=InnoDB;

      • shut down the server normally;
      • start 10.3 or 10.4 server on the same datadir;
      • (optionally, it doesn't affect the outcome) run mysql_upgrade;
      • run 

        CHECK TABLE t1;
        		 
        ALTER TABLE t1 DROP CONSTRAINT IF EXISTS x;

        The result is

        Table	Op	Msg_type	Msg_text
        		 
        test.t1	check	status	OK
        		 
        ERROR 1932 (42S02) at line 2: Table 'test.t1' doesn't exist in engine

        The error log gets the warning:

        2019-05-27  1:49:53 9 [Warning] InnoDB: Table test/t1 contains 1 user defined columns in InnoDB, but 2 columns in MariaDB. Please check INFORMATION_SCHEMA.INNODB_SYS_COLUMNS and https://mariadb.com/kb/en/innodb-data-dictionary-troubleshooting/ for how to resolve the issue.

        Further attempts to use the table cause errors in the log:

        2019-05-27  1:50:18 10 [ERROR] InnoDB: Table `test`.`t1` is corrupted. Please drop the table and recreate.

      A datadir pre-created as described on 10.1 aaf53ea0 is attached.

      Not reproducible with 10.2, either being the new server or old server in the scenario.
