Indeed. The k vs K idea is an excuse for not wanting to side with
either camp, but it does not scale.

I'd imagine that one of the first things someone will want to try is
something like SET work_mem TO '10MB', which will fail or misbehave
because 10000000 bytes do not divide up into chunks of 1024 bytes. Who
wants to explain to users that they have to write '10MiB'?
Since about forever, PostgreSQL has used kB, MB, GB to describe memory
allocation. If we want to change that, we ought to do it across the
board. But that's a big board.
