**#{SCHEMA_NOT_UPDATED_MESSAGE_SHORT}**
Usually, when adding new %<migrations>s, %<schema>s should be
updated too (unless the migration isn't changing the DB schema
and isn't the most recent one).
MSG
DB_MESSAGE = <<~MSG
This merge request requires a database review. To make sure these
changes are reviewed, take the following steps:
1. Ensure the merge request has ~database and ~"database::review pending" labels.
If the merge request modifies database files, Danger will do this for you.
1. Prepare your MR for database review according to the
[docs](https://docs.gitlab.com/ee/development/database_review.html#how-to-prepare-the-merge-request-for-a-database-review).
1. Assign and mention the database reviewer suggested by Reviewer Roulette.
MSG
DB_FILES_MESSAGE = <<~MSG
The following files require a review from the Database team:
MSG
DB_REMOVE_MESSAGE = <<~MSG
If you no longer require a database review, you can remove this suggestion
by removing the ~database label and re-running the [`danger-review` job](#{ENV['CI_JOB_URL']}).
MSG
DB_MIGRATION_TESTING_REQUIRED_MESSAGE = <<~MSG
The [database migration pipeline](https://docs.gitlab.com/ee/development/database/database_migration_pipeline.html)
must be triggered by the job `db:gitlabcom-database-testing` must be run before requesting
~database review. This job takes ~30m and will post the results to a comment on the merge
request. Please run and review any results before passing to a reviewer.

⌛ **Migration Timestamp Out of Date**
The following migrations have timestamps that are over three weeks old:
