+* Bring back `db:test:prepare` to synchronize the test database schema.
+
+ Manual synchronization using `bin/rake db:test:prepare` is required
+ when a migration is rolled-back, edited and reapplied.
+
+ `ActiveRecord::Base.maintain_test_schema` now uses `db:test:prepare`
+ to synchronize the schema. Plugins can use this task as a hook to
+ provide custom behavior after the schema has been loaded.
+
+ NOTE: `test:prepare` runs before the schema was synchronized.
+
+ Fixes #17171, #15787.
