Here's a kludged-together work-around. After you do your rare pool requests, drop the sequence and recreate it starting at MAX(ID)+1. There is no easier way to reset the sequence number.

because the pool request will be rather rare, the rest of the time the IDs will be generated one by one

what I thought of is having two sequences and split the range of possible IDs between them (i.e. the first half is handled by one-by-one sequence and the second half is handled by the pool sequence) but this seems quite lame (the relative order of IDs of the rows will be ruined)
