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.
