Can you explain what you mean by "put it in a domain" - I'd love extra

Domains are basically type aliases with an optional CHECK clause, so
you could do something like:
CREATE DOMAN sales_tax_rate AS DECIMAL(5,5) CHECK (VALUE >= 0);
Then, you can use the type "sales_tax_rate" in your tables, etc. just
as a normal first-class type. (The only limitation, right now, is
that you can't create an array of them.)
In response to the other email, DECIMAL is definitely the better
solution for what you are looking for.
