The two main limitations are that you are creating a entirely new query language format and that the name of the database is constant and determined at the time of connection to the database. >From a practical perspective I do not believe it (as written exactly above) >can done without breaking existing functionality and/or introducing >ambiguities. As I am not a PostgreSQL developer myself I cannot be of much more help but ISTM that providing more why and less what would get you better advice. As to learning how to contribute to the project I will let others point you to the existing resources that are out there. It would, however, probably help to explain what skills and background you already posses.
