I do know that, I wrote the bit in the docs explaining that that's
possible...

But using replication connections that way in psql makes requires it to
be invoked in a different way and makes it it impossible to specify the
database name in a normal way etc. You can also run into commands that
give you 'unexpected result status' errors and such. I don't think
that's a good default interface.
