For logical replication there is no need to implement this, but others are
using the pgoutput plugin for Change Data Capture. The reason they are
using pgoutput is because it is guaranteed to be available as it is in core
postgres.

Implementing LogicalDecodeMessageCB provides some synchronization facility
that is not easily replicated.

Thoughts ?
