There is no straightforward way to extract such information, particularly if the commit log is missing. If that file is from a base backup, there is the additional difficulty that the file could be in an inconsistent state. You would have to hire a specialist for such work. It sounds like you should consider letting somebody more reliable than your software vendor manage your database backups.
