POLA violation with \c service=

Folks,

I've noticed that psql's  \c function handles service= requests in a
way that I can only characterize as broken.

This came up in the context of connecting to a cloud hosting service
named after warriors or a river or something, whose default hostnames
are long, confusing, and easy to typo, so I suspect that service= may
come up more often going forward than it has until now.

For example, when I try to use

\c "service=foo"

It will correctly figure out which database I'm trying to connect to,
but fail to notice that it's on a different host, port, etc., and
hence fail to connect with a somewhat unhelpful error message.

I can think of a few approaches for fixing this:

0.  Leave it broken.
1.  Disable "service=" requests entirely in \c context, and error out if attempted.
2.  Ensure that \c actually uses all of the available information.

Is there another one I missed?

If not, which of the approaches seems reasonable?

Cheers,
David.
