[ looks... ] Oh, NV is a "double", which I think would be a perfectly
reasonable choice: it'd be exact up to about 2^53, on most machines,
which should be plenty for a long time to come.
How much of a user-visible change would that be, if the "processed"
field of a spi_exec_query() result started coming back as an NV not
an IV? I'm not sure how much that would affect semantics in typical
Perl code.
