Looking at the plpgsql code, it's clear that what's actually implemented
RAISE level string-literal [ , variable [ , variable [ ... ] ]
which is pretty bletcherous; seems like it should accept a list of
expressions instead. But for 7.1, I guess this is a documentation bug
rather than something to change in the code.
