The error message isn't very helpful, but the issue here is that you're
doing a completely useless SELECT --- or at least plpgsql thinks it's
useless, because you're discarding the result. (I think that plpgsql is
being overly anal-retentive about it, since such a query might indeed be
useful if you then examine FOUND or ROW_COUNT, but that's the issue at
the moment.) Try making it a SELECT INTO instead.
