The pq_sequence() call will set the product-queue cursor to the data-product 
just after the one the cursor currently references. If that data-product 
exists, then the subsequent pq_seqdel() should delete that product. Both the 
pqutil(1) and pqexpire(1) programs use pq_seqdel() -- so you might examine them.

It might be best to set the 4th argument of pq_seqdel() to a non-zero value so 
that the function waits on any locks.
