Review comment:
I bring this up because I don't think we should simply add this extra work
for _all_ callers (as I see you did in the last commit Bruno); it's only
unusual cases where this might happen. You might first remove them all and
tell us what tests reveal which queries need this, then put the zero check only
for them.
