-- country is taken from ISO 3166

-- probably ought to add a note about analyze for efficiency on non-integer primary keys

create table countries (
    -- this violates 3nf but is used for 2 reasons
    -- 1. to help efficiency
    -- 2. to make querys not fail if no translation exists yet
    default_name varchar(100)

        constraint countries_iso_pk

);

comment on table countries is '
    This is the country code/english name table from ISO 3166.
';

comment on column countries.default_name is '
    This is admittedly a violation of 3NF but it is more efficient and helps with non-translated values.
See country.sql for more comments.
