I can't find any reference to that on this page? The following does indeed say:
<URL:http://en.wikipedia.org/wiki/JEDEC_memory_standards>
<quote>
kilo (K): A multiplier equal to 1,024 [..] The specification notes
that these prefixes are included in the document only to reflect
common usage. It refers to the IEEE/ASTM SI 10-1997 standard as
stating, that "this practice frequently leads to confusion and is
deprecated".

If you want to make the difference explicit, consider using "KiB"
(1024, note the extra "i") vs. "kB" (1000); although doing so is
probably not consistent with any other uses in PostgreSQL.

The unit symbol for the kibibyte is KiB. The unit was established by
the International Electrotechnical Commission (IEC) in 1999 and has
been accepted for use by all major standards organizations.
