    Description

      The problem described in MDEV-28067 is also repeatable on the table level:

      CREATE OR REPLACE TABLE t1 (a CHAR(10)) COLLATE latin1_swedish_ci COLLATE latin1_bin;
      		 
      SHOW CREATE TABLE t1;


      +-------+------------------------------------------------------------------------------------------------------------------------------+
      		 
      | Table | Create Table                                                                                                                 |
      		 
      +-------+------------------------------------------------------------------------------------------------------------------------------+
      		 
      | t1    | CREATE TABLE `t1` (
      		 
        `a` char(10) COLLATE latin1_bin DEFAULT NULL
      		 
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_bin |
      		 
      +-------+------------------------------------------------------------------------------------------------------------------------------+

      The expected behaviour would be to return a "conflicting declarations" error.

      The problem is also repeatable on the database level:

      CREATE OR REPLACE database db1 COLLATE latin1_swedish_ci COLLATE latin1_bin;
      		 
      SHOW CREATE DATABASE db1;


      +----------+-----------------------------------------------------------------------------------+
      		 
      | Database | Create Database                                                                   |
      		 
      +----------+-----------------------------------------------------------------------------------+
      		 
      | db1      | CREATE DATABASE `db1` /*!40100 DEFAULT CHARACTER SET latin1 COLLATE latin1_bin */ |
      		 
      +----------+-----------------------------------------------------------------------------------+
