Add command to query for incomplete batched background migrations
GitLabSOS already captures the status of DB migrations, I think it would be beneficial to also capture the status of incomplete batched background migrations.
It would be to add to the cmd list the following:
{ cmd: 'gitlab-psql -c "SELECT job_class_name, table_name, column_name, job_arguments
FROM batched_background_migrations
WHERE status <> 3;"',
result_path: 'gitlab_batched_migrations' }
