I think if it would have been unsigned we could have got more range, as anyways negative numbers doesn't make sense as PK's, of course reaching the 2^63-1 is remote (or probably impossible)

SQLite stores ROWIDs as signed 64-bit integers. Such an integer can represent 2^64 distinct values, in the range [-2^63, 2^63-1]. 2^63 is not representable, it wraps around to -2^63.
