I recommend starting with the documentation. It sounds like you'd like
to do pl/pgsql stuff, so you might try this link:
http://www.postgresql.org/docs/8.2/interactive/plpgsql.html. Take
sample functions from there, and adapt them to do what you need. It's
easier to take something that works and learn the postgresql idioms
from that rather than to take something from MS SQL and try to replace
MS SQL-isms with PostgreSQL-isms.
