[debian-mysql] Bug#866751: wrong table structure for innodb_table_stats

[Marc Haber]

Package: mariadb-server-10.1
Version: 10.1.23-9+deb9u1
Severity: normal

Hi,

after upgrading to stretch from a jessie that already had MariaDB 10.0
(10.0.30-0+deb8u2 to 10.1.23-9+deb9u1), MariaDB complains on startup in
the error.log:

2017-07-01 15:14:37 7fb55d15d700 InnoDB: Error: Column last_update in table "mysql"."innodb_table_stats" is INT UNSIGNED NOT NULL but should be BINARY(4) NOT NULL (type mismatch).
2017-07-01 15:14:37 7fb55d15d700 InnoDB: Error: Fetch of persistent statistics requested for table "mysql"."gtid_slave_pos" but the required system tables mysql.innodb_table_stats and mysql.innodb_index_stats are not present or have unexpected structure. Using transient stats instead.

Can I ignore this? If no, how do I fix this? Does this happen often
enough so that an automatic table structure migration is in order?

Greetings
Marc
