Reading your post, your "modules" are not independent, since they contain migrations that modify tables created by other modules. Assuming your modules were independent, you could start with an empty database, run just the particular module's migration files on it, and then dump the schema of the result. But that's not the case. Let me take a step back and ask what you are trying to accomplish. If you have a module with two migration files, why do you want the (incomplete/ambiguous) schema for the combination of those two files (which can't even work if the module's migrations depend on other modules' migrations)? Are you just looking to combine two or more migration files into a single file? If so, why? >From my current understanding of your description of the problem, there is no solution, because you are asking for something that does not exist (a database schema for the result of multiple migrations that alter tables not created in previous migrations). That suggests that either my understanding is incorrect or your design is confused. Hopefully the former. This is probably just a communication issue, as I'm guessing English is not your first language. If anyone has a better idea about what the coolesting wants, please chime in.
