BayesStore MariaDB on EL9

Hi!

I am trying to use a mariadb database as bayesstore, but it fails to 
load tokens. Whenever it tries to insert something into bayes_token it 
fails with an error

dbg: bayes: _put_token: SQL error: Data too long for column 'token' at row 1

The table has been created as mentioned in

https://github.com/apache/spamassassin/blob/trunk/sql/bayes_mysql.sql

but the 5 byte binary isn't big enough. I have tried with sa-learn 
--restore as well as learning some spam mails. bayes_token remains empty.

MariaDB [spamassassin]> show create table bayes_token\G
*************************** 1. row ***************************
        Table: bayes_token
Create Table: CREATE TABLE `bayes_token` (
   `id` int(11) NOT NULL DEFAULT 0,
   `token` binary(5) NOT NULL,
   `spam_count` int(11) NOT NULL DEFAULT 0,
   `ham_count` int(11) NOT NULL DEFAULT 0,
   `atime` int(11) NOT NULL DEFAULT 0,
   PRIMARY KEY (`id`,`token`),
   KEY `bayes_token_idx1` (`id`,`atime`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_swedish_ci
1 row in set (0.000 sec)

Any idea what goes wrong here?

Thanks,

Gerald
