The behaviour of SELECT * is well defined and consistent across many
databases, so I don't like changing the behaviour of it.

I would be in favour of a different symbol which expands to a more
selective column set. Perhaps by default it picks up short textish columns;
skip bytea or long text fields for example but can be adjusted with HIDDEN.
Perhaps "SELECT +"?
