Fix missing genre and tag data on MusicBrainz mirror server

A bug (MBS-12508) in the upgrade script of MusicBrainz Server’s latest schema-change release caused aggregate genre and tag data (if you had imported any) to be deleted.

You can safely ignore this section if:

• you’re not running a mirror server;
• you don’t make use of genre or tag data;
• you’ve already done a full re-import of your database after the schema change release.

To restore the genre and tag data, follow these steps:

1. Turn off cron jobs:

   admin/configure rm replication-cron
   sudo docker-compose up -d musicbrainz

2. Ensure you’ve replicated up to the most recent replication packet available. If you’re not sure, run:

   sudo docker-compose exec musicbrainz replication.sh & \
   sudo docker-compose exec musicbrainz /usr/bin/tail -f mirror.log

   and see what it tells you; if you’re up-to-date, it should say “Replication packet … is not available.”

3. Run:

   sudo docker-compose exec musicbrainz ./admin/sql/updates/20220720-mbs-12508.sh

4. Turn cron jobs back on:

   admin/configure add replication-cron
   sudo docker-compose up -d musicbrainz

You can verify that this process worked by checking that the number of tags in the database is over 200,000:

sudo docker-compose exec musicbrainz bash -c "echo 'SELECT count(*) FROM tag' | ./admin/psql READWRITE"

Only change
