 * Purpose: For PostgreSQL, MySQL and MariaDB:                                *

 *          stoires DBMS version as integer: MMmmuu                           *

 *          M = major version part                                            *

 *          m = minor version part                                            *

 * Example: if the original DB version was 1.2.34 then 10234 is set           *

 *                                                                            *
