Mmph. I just don't see any benefit in being able to start a command in the middle of a line. Even if it's not dangerous to future things we might want o implement, I'd argue it's still poor style, and of no practical utility. But if I lose that argument, then I do. >>> Shall I make a patch that allows backslash-newline to be handled this way >>> in both psql and pgbench backslash commands? > >> I certainly don't object to such a patch, although if it's between you >> writing that patch and you getting Tomas Vondra's multivariate >> statistics stuff committed, I'll take the latter. :-) > > I'll get to that, but I'd like to get this area fully dealt with before > context-swapping to that one.
