Revoking public execute on it by default would definitely make me
happier.  I could be swayed either way on the explicit super-user check
in the function itself.  In the general case, imv we should at least
attempt to consider the risk involved in improper handling of the
permissions around super-user-only functions.  Higher risk implies an
extra check in the code to force use of SECURITY DEFINER functions to
work around it, in an attempt to impart the severity of the risk.

Thinking about it a bit more, I'd honestly like to see the check there
for dblink().  That's not entirely fair of me though I suppose, I really
don't feel comfortable with dblink() to begin with and don't expect I'll
ever use it. :)
