Обсуждение: UNIQUE constraint fails

With 7.1b4:

test=# create table auction_type(id serial,login text,birthday timestamp);

test=# create table auction(unique(login)) inherits("auction_type");
ERROR:  inherited attribute "login" cannot be a PRIMARY KEY because it is not marked NOT NULL

But I didn't ask that "login" be a PRIMARY KEY, only a UNIQUE. What's
going on there?

Cheers,

Thanks Tom.
