I think this coding should be rejected, but evidently it's not.  My
understanding of "record" in plpgsql is that it's just a placeholder
name for a tuple type determined elsewhere.  In this situation the
exact type of x is never determined, and so you shouldn't be able to
assign to fields of x.  Ooops.

In the meantime, it might work if you declare "x magic" instead of
"x record".
