While we're on the subject, the units used by pg_size_pretty() are
incorrect, at least according to the IEC: for example, "MB" is
strictly-speaking one million bytes, not 1024^2 bytes. 1024^2 bytes is 1
MiB (similarly for KiB, GiB, and TiB). I'll take a look at fixing this
as well, barring any objections.
[ itch... ] The IEC may think they get to define what's correct, but
I don't think that squares with common usage. The only people who
think MB is measured in decimal are disk-manufacturer marketroids.
That isn't entirely accurate, unfortunately. Telecom also generally
uses decimal. I'm as unhappy with the current situation as anyone but
it's not just disk makers & marketing folks, even amoung the computing
industry.
Telcos don't tend to follow standard computer industry thinking...
Kilo, Mega and so on are used as decimal exponent multiples to SI units,
like meter, gram, .... There's no such thing as a byte as physical unit,
it's completely artificial.
pg_size_pretty follows the standard of "df -h" or "du -h" and so on,
which use the well-known 1024-multiples, as every sane user of bytes will.
