> Consuming messages from pages with a db as persistence backend leaves commit records in message_table which doesn't get cleaned up. Seems that depaging does not add txids to internal map.
> SQL script for cleanup (no known side effect):
> {code}
> DELETE
> FROM MESSAGE_TABLE
> WHERE txid IN
>     (SELECT txid
>      FROM
>        (SELECT count(*) AS cnt,
>                txid
>         FROM MESSAGE_TABLE
>         WHERE txid IN
>             (SELECT txid
>              FROM MESSAGE_TABLE

>         GROUP BY txid)AS m
