Right. I'd tried doing something with INOUT and OUT parameters, but I
wasn't able to figure out how to do with oid[] what I'd do with
oidvector. On the bright side, what I did does do the right thing if
there are named IN parameters, which was part of what I was trying to
fix.

Speaking of said psql's columnar representations, what about the
alignment thing proposed earlier where an embedded newline doesn't
mess up the alignment of everything else? Is there some generic way
to handle this?
