It's not a "simple feature". As you have it, it's a non-orthogonal wart.
It's like telling users that the return key only works in \set commands
and elsewhere you have to type shift-return to end a line. I'm fine with
setting up a global policy that backslash-newline works to continue
backslash commands across lines, but I'm not fine with saying that it
only works in \set. That's just weird, and the fact that you can do it
with a trivial patch doesn't make it less weird. You're proposing to
put a new cognitive load on users because you can't be bothered to write
a patch that's not half-baked. We don't do things like that around here.
FWIW, I looked a bit further and concluded that probably psqlscan.l
doesn't need to be modified; so likely you could do this across all of
pgbench's commands without touching psql. That might be an acceptable
compromise for now, though I still think that as soon as we have this
for pgbench, users will start wanting it in psql.
