I've seen the syntax for using a lookup table in a CHECK() constraint,

I cannot find a reference to it. It's not in Section 5.3.1 of the 8.2 docs.
Specifically, I want to reference a table of ISO 2-letter codes for US
states and Canadian provinces/territories in a table with name and address
columns.
Please point me to a reference.
You could use a function, or a foreign key.
