Actually we use the Postgres service offered by Azure (Flexible server). So, I was looking at the following documentation which talks about Logical Replication and Logical Decoding as two different methods of replication. Here Logical replication talks about creating both Publisher and Subscriber settings using simple SQL statements. While for Logical decoding its talking about publishing WAL but not on how to consume this WAL.
Also Logical Replication has some limitations like materialized views, sequences being not replicated. While DDL changes propagation is a common deficiency among both Logical decoding and Logical Replication. Am I reading this correctly?

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.
