I agree that driver integration, and in particular JDBC integration,
is important and needs some thought. I don't think it horribly
matters, with a feature like this, what shows up when people type
stuff into psql. Whatever it is, people will get used to it. But when
they interact through a driver, it's different. It is no good
inventing things, either in PostgreSQL or in the JDBC driver for
PostgreSQL, that make PostgreSQL behave differently from every other
database they use. I don't know exactly how we get to a good outcome
here, but I think it's worth some careful consideration.
