Hi,
For the procedure part, you might want to take a look at pgTSQL:
pgTSQL enables you to run some parts of T-SQL code in PostgreSQL. Coverage is not complete by any means. As others have written, it all depends on how much T-SQL code you have in your database and application. Migrating the schema and data is fairly painless. But the amount of code you have will determine whether it's a 1-day or 1-month exercise.
