It is. For instance shared_buffers is configured as the number of
buffers. What we're talking about here is ways to specify the intended
usage with other units (eg "I want N megabytes of shared buffers") but
that's not going to magically let you allocate half a shared buffer.
Peter's not said exactly how he plans to deal with this, but I suppose
it'll round off one way or the other ...
