I'm having trouble viewing the jenkins results. It LGTM, but I want to see what the error reported is.

LGTM

Two questions:

Which manual tests have you done (since the checkbox was marked)?
Are there any issue open for the duplication of error definitions (errno/errname.go vs parser/mysql/errname.go)?

Which manual tests have you done (since the checkbox was marked)?

Changing the authentication plugin of an account:

TiDB> CREATE USER 'u1'@'%' IDENTIFIED WITH 'auth_socket';
Query OK, 0 rows affected (0.0172 sec)

TiDB> SHOW CREATE USER 'u1'@'%'\G
*************************** 1. row ***************************
CREATE USER for u1@%: CREATE USER 'u1'@'%' IDENTIFIED WITH 'auth_socket' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK
1 row in set (0.0021 sec)

TiDB> ALTER USER 'u1'@'%' IDENTIFIED WITH 'mysql_native_password' BY 'foobar';
Query OK, 0 rows affected (0.0063 sec)

TiDB> SHOW CREATE USER 'u1'@'%'\G
*************************** 1. row ***************************
CREATE USER for u1@%: CREATE USER 'u1'@'%' IDENTIFIED WITH 'mysql_native_password' AS '*9B500343BC52E2911172EB52AE5CF4847604C6E5' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK
1 row in set (0.0019 sec)

Using an invalid authentication plugin name:

TiDB> ALTER USER 'u1'@'%' IDENTIFIED WITH 'pumpkin_password';
ERROR: 1524 (HY000): Plugin 'pumpkin_password' is not loaded

TiDB> CREATE USER 'u2'@'%' IDENTIFIED WITH 'pumpkin_password';
ERROR: 1524 (HY000): Plugin 'pumpkin_password' is not loaded

Using SET PASSWORD on an account that uses auth_socket:

TiDB> CREATE USER 'u3'@'%' IDENTIFIED WITH 'auth_socket';
Query OK, 0 rows affected (0.0170 sec)

TiDB> SET PASSWORD FOR 'u3'@'%' = PASSWORD('foobar');
Query OK, 0 rows affected, 1 warning (0.0167 sec)
Note (code 1699): SET PASSWORD has no significance for user 'u3'@'%' as authentication plugin does not support it.

Are there any issue open for the duplication of error definitions (errno/errname.go vs parser/mysql/errname.go)?

Yes, #29026
