The table structures shouldn't be a problem to do fairly mechanically,
and at worst you can simply hand-type in the data. The stored
procedures will be a problem at two levels:

1. You'll have to translate them into a language PostgreSQL can use
from (I'm guessing here, but it's usually a good guess in these
situations) T-SQL.

2. PostgreSQL functions, which are similar in many ways to stored
procedures, have a fundamental difference: they can't control
transactions. Any stored procedures that have a COMMIT or ROLLBACK in
them will have to be re-architected in a fundamental way.

Cheers,
David.
