I was using the flag table to keep the flags consistent between all the tables in the database that might use them. I didn't know about CREATE DOMAIN which will do what I want perfectly
Note that DOMAIN support unfortunately isn't perfect; for example, plpgsql doesn't enforce domain constraints (IIRC there's some other bugs as well). So you should probably do a test to make sure everything you'll be doing with domains will work before you re-code everything.
Also, I suggest using "char" instead of just char. "char" is a special data type that's limited to storing a single character; the advantage is that it's much smaller and faster than a char.
If you do end up back at using foreign keys, I suggest using either a smallint or "char"... the savings across the number of fields you're looking at would start to add up, especially if you start putting a decent number of rows in the table.
