There's no need to replicate the contents of a view, as it doesn't contain any data.

pglogical can replicate the initial schema, including any views, but won't replicate DDL changes automatically after
that.It does provide a clean way to replicate DDL from the master to slaves with pglogical.replicate_ddl_command().

https://www.2ndquadrant.com/en/resources/pglogical/- installation isn't too painful (though the docs are a little
sparsewhen it comes to which node you should run which command on. Make the postgres.conf changes on master and slave
nodes,as slave nodes need replication slots too(?)).
