Hi, As far as I can tell, you can't restrict the length of a ci_text field like char(5) or varchar(5)? Let's say you got a stock table and you want an alphanumeric stock code that is the primary key but it must be case insensitive can I do something like this: create table stock(stock code varchar(5), stock_desc varchar(50)) primary key pk_stock_code ilike(stock_code) Will this work? Is this the right syntax? Thanks H.F. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
