Assuming your goal is compatibility to a level such that no changes are
required in the client application, I'd say it'd be a tremendous amount
of work. At the very least you'd have to reverse-engineer mssql
server's communication protocol and write a proxy that could understand
and translate that to something compatible with postgresql. Then you'd
have to deal with the difference between the two server sql dialects.
All in all, you'd be much better off designing your application such
that it explicitly supports multiple databases to begin with.
