Re: how to set more than two attributes as primary keys in a table

You might also find unique () to be very helpful.  I personally prefer to
always have an id column as the primary key in any table, and to further
constrain the table with unique's, where necessary.

create table foobar (
    id    bigint default nextval(foobar_seq),
    foo    varchar(32),
    bar    smallint,
    foob    text,
    primary key (id),
    unique (foo, bar)
);

Vertu sæll,
