When creating, dropping, or revoking roles, changing a user password to null, locking users manually, or auto-locking a user for violating some condition of their login policy, the database server ensures that the number of role administrators will not drop below the specified minimum. Only role administrators with non-null passwords, including those with expired passwords, and who are not locked out are included in the count.

Changes to the value of this option are allowed only if each role has at least the specified number of role administrators. While revoking a role from a user, if the number of role administrators falls below the min_role_admins option value, the statement returns an error.
