So?  There are lots of surprising things in SQL.  And *of course* the
only complaints come from people who didn't know about it, not from
satisfied users.

The reason people don't know about this feature is that it's so poorly
documented --- there's just one mention buried deep in chapter 35 of
the manual, in a place where most people wouldn't think to look for it.
I'm not quite sure where's a better place though.
