Please keep in mind, that most replication solutions (that I know of)
are quite independent from the PostgreSQL version used. Thus,
documenting which version of PostgreSQL can be used with which version
of a replication system should better be covered in the documentation of
the replication system. Otherwise you would have to update the
PostgreSQL documentation for new releases of your favorite replication
system - which seems to lead to confusion.

I agree that having such a 'replication guide for users of PostgreSQL'
is a good thing to have. But I think not much of that should be part of
the official PostgreSQL documentation - mainly because the replication
solutions are not part of PostgreSQL.
