I don't think so; especially since the proposed fix doesn't help on
systems where we are using the native printf.

I think that patch could use more thought.  As is, it will print

    connect to new database (currently "none")

which to me is claiming that we are connected to a database whose name
is "none".  The quotes should not be used in this situation, and in
fact it would be better for translatability if the whole message text
were specialized to this case.  I'd like to see it reading more like

    connect to new database (currently no connection)
