I don't see how, if it is not functionality that has been explicitly or
implicitly promised. The fact that it isn't what you expected doesn't
make it a bug.
There's a natural tendency to want to call things bugs at this stage of
the cycle so that they qualify for application, but there's a reason we
have a freeze, and it needs to be adhered to.
If we're going to do backwards compatibility for psql then we need to do
it in a fairly comprehensive way, not bit by bit, because we can
reasonably say either "we support backwards compatibility" or "we don't
support backwards compatibility", but we cannot reasonably say "we
support backwards compatibility just for these commands" - that's way
too confusing. The task is probably non-trivial - just look at pg_dump.
Might be another good starting hackers project.
