From the developer:
DBDiff is an ODBC database utility that performs a comparison between two databases.
Any database that supports ODBC access can be used. The databases DO NOT have to be of the same type, they don¿t even need to be on the same machine, as long as they are both accessible from the machine running DBDiff.
You may want to check out more software, such as EMS SQL Manager 2005 for PostgreSQL, Mybase or EMS SQL Manager 2007 for Oracle, which might be related to DbDiff.
