In plpgsql (at least in the current implementation) an OUT parameter is
pretty much just a local variable, and so there's no efficiency argument
against using it as a temporary. Whether you consider this good style
is a matter of opinion.

Not really an issue in Postgres: we do not support pass-by-reference
parameters and are unlikely to start doing so. There isn't any way
that you can affect locals of a calling procedure before you return.
