PS4, Line 56: Estimate
An alternative would be having sort of Pop() method that removes the last 
actually added row.

Probably, if targeting for success most of the times (i.e. not going over a 
limit on the size of the result protobuf), the alternative approach is better 
if thinking about the performance.  From the other side, adding a big row might 
involve costly memory re-allocations and memcpy() which will be wasted if 
removing the last added element.

What do you think?
