workarounds for ci_text - Mailing list pgsql-general

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.
