Right. There's comment.sql but it's about comments in language and not comments on database objects. It looks like the COMMENT ON for various objects is tested in test files for those objects and there isn't any tests testing databases e.g. ALTER DATABASE in sql directory. > Should we need also add test cases for this kind of > objects? > Possibly, we don't have those testcases, because those will affect existing objects when run through "make installcheck". But current database is always going to be "regression" for these tests. That database is dropped when installcheck starts. So, we can add a testcase for it. But I am not sure where should we add it. Creating a new file just for COMMENT ON DATABASE doesn't look good. > >> Instead of changing get_object_address_unqualified(), >> get_object_address_unqualified() and pg_get_object_address(), should >> we just stick get_database_name(MyDatabaseId) as object name in >> gram.y?
