+-- ATTENTION CODE REVIEWER
+-- If this file has been updated, please make sure to check
+-- whether this test failed before that happened:
+-- "Test.Syd.Persistent.PostgresqlSpec.persistPostgresqlSpec.Can automatically migrate from the previous database schema"
+-- If this test failed beforehand, but this golden test has
+-- been updated anyway, that means the current migration is
+-- dangerous with respect to the current database.
