built-in logical replication is good example to start looking for.

Between Logical replication and Logical Decoding we came up with Logical decoding as the choice due to limitation of logical replication (materialized views, external views/tables, sequences not replicated). However we are not finding a good example with instructions on how to set up a consumer postgre server.

Logical decoding is the process to convert WAL to a logical change,
logical replication deals with transferring these changes to another
server and applying those there. So they work in tandem; just one
without the other can not be used. So I am confused about your
requirements.
