No. Primary keys are not guaranteed to be in sequence without
"holes". You may use a stored procedure or something like that to
increment a counter - beware of rollbacks.
If there is no requirement for a real sequence without holes, pk may
work. Or, depending on the database, any mechanism that can be used
for integer pk generation.
