If you're porting from T-SQL, you should use PL/pgSQL. However, you will have
to re-code many of your procedures by hand, as T-SQL and PL/pgSQL have
substantially different syntax for control structures and cursors.
See the porting articles on techdocs.postgresql.org

You should upgrade to the 7.3.4 if possible as it has some bug fixes missing
in 7.3.2.
