Kenneth,

While this isn't the question you asked, might I encourage you to use DOMAINs
instead? I.e.:
CREATE DOMAIN abc_col AS TEXT
CHECK VALUE IN ( 'a', 'b', 'c' );
Then you declare the table as:
table (
field abc_col,
);
I find that DOMAINs give vastly enhanced managability compared to table
constraints.
