I knew that pgsql does that, because I made sure it did ;-). But it is
pretty interesting that these other DBMSes also go out of their way to
produce a specific error. As you say, that suggests that they could
have accepted it, if they'd wanted to, at least from the standpoint of
not having a grammar structure problem.
