Re: replacing mysql enum

While this isn't the question you asked, might I encourage you to use DOMAINs 
instead?   I.e.:

CREATE DOMAIN abc_col AS TEXTCHECK 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.
