That seems awful. If a user says "SELECT * FROM tab" and it fails,
how are they supposed to recover, or even understand what the problem
is? I think we should really try to at least generate an errcontext
here:
ERROR: integer out of range
CONTEXT: while generating virtual column "b"
And maybe a hint, too, like "try excluding this column".
