None that I know of, but all of those should happily be able to point
at a PostgreSQL database (at least jdbc and odbc, since it's what
they're designed for; I'm assuming python can do it too).

A bigger issue you're likely to run into is that unless your programs
are using only the barest, simplest commands you're likely to run
into syntax compatibility issues. If that's the case you'll either
need to port the code (there is a tool out there somewhere that might
help with that), or you can try our (commercial) product.
