Adding a new column in INFORMATION_SCHEMA.COLLATIONS:
PAD_ATTRIBUTE ENUM('PAD SPACE','NO PAD')
and a new column Pad_attribute into SHOW COLLATION.
The new column has been added after SORTLEN but before COMMENT.
This order is compatible with MySQL-8.0 order,
with the exception that MariaDB has an extra last column COMMENT:
MariaDB [test]> desc information_schema.collations;
+--------------------+----------------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------------------+----------------------------+------+-----+---------+-------+
| COLLATION_NAME | varchar(64) | NO | | NULL | |
| CHARACTER_SET_NAME | varchar(32) | YES | | NULL | |
| ID | bigint(11) | YES | | NULL | |
| IS_DEFAULT | varchar(3) | YES | | NULL | |
| IS_COMPILED | varchar(3) | NO | | NULL | |
| SORTLEN | bigint(3) | NO | | NULL | |
| PAD_ATTRIBUTE | enum('PAD SPACE','NO PAD') | NO | | NULL | |
| COMMENT | varchar(80) | NO | | NULL | |
+--------------------+----------------------------+------+-----+---------+-------+
The new Pad_attribute in SHOW COLLATION has been added as the last column.
This is also compatible with MySQL:
MariaDB [test]> show collation like 'utf8mb4_bin';
+-------------+---------+------+---------+----------+---------+---------------+
| Collation | Charset | Id | Default | Compiled | Sortlen | Pad_attribute |
+-------------+---------+------+---------+----------+---------+---------------+
| utf8mb4_bin | utf8mb4 | 46 | | Yes | 1 | PAD SPACE |
+-------------+---------+------+---------+----------+---------+---------------+
