According to T42626 the timestamp columns should be adjusted from varbinary(14) to binary(14) because there is no need to hold infinite.

And globaluser.gu_enabled is using DEFAULT '' which is not a valid timestamp.

Affected columns:

• globaluser.gu_enabled
• globaluser.gu_registration
• globaluser.gu_password_reset_expiration
• localuser.lu_attached_timestamp
• renameuser_queue.rq_requested_ts
• renameuser_queue.rq_completed_ts

Unaffected, because it has to hold infinite

• global_user_groups.gug_expiry

Correct type:

• globaluser.gu_email_authenticated
