See for example
http://www.postgresql.org/message-id/20099.1350484290@sss.pgh.pa.us
that this is known and accepted behaviour.
However,
http://www.postgresql.org/message-id/22259.1114613632@sss.pgh.pa.us
so I guess that it was not intended, but since it has been that way
for long enough it would be too painful to change it.

So actually my original answer "it is by design" is probably wrong.

"Based upon" should be read as "inspired by" rather than
"compatible with".
