I think that the typical use-case of \c is to connect to another database
on the same host, at least that what I do pretty often. The natural
expectation is that the same "other" connection parameters are used,
otherwise it does not make much sense, and there is already a whole logic
of reusing the previous settings in psql, at least wrt describing the
target (host, port, user…).

I think that we should fix the behavior rather than document the current
weirdness. I do not think that we should introduce more weirdness.
