Anything is possible but what you are trying to do makes little sense generally and would take a tremendous amount of
workto be done in PostgreSQL. The two main limitations are that you are creating a entirely new query language format
andthat 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
functionalityand/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
wouldget you better advice. As to learning how to contribute to the project I will let others point you to the
existingresources that are out there. It would, however, probably help to explain what skills and background you
alreadyposses.
