I guess this is reasonable, but how do I know what slot name do I have
to create?  Maybe it'd be better to be explicit about that:

HINT: You should create slot \"%s\" manually, enable the subscription, and run %s to initiate replication.

though this still leaves a lot unexplained about that slot creation
(which options do they have to use).


If this sounds like too much for a HINT, perhaps we need a documentation
subsection that explains exactly what to do, and have this HINT
reference the documentation?  I don't think we do that anywhere else,
though.
