A synchronous standby can be a physical replication standby or a logical
replication subscriber. It can also be any other physical or logical WAL
replication stream consumer that knows how to send the appropriate
feedback messages. Besides the built-in physical and logical replication
systems, this includes special programs such
as <command>pg_receivewal</command> and <command>pg_recvlogical</command>
as well as some third-party replication systems and custom programs.
Check the respective documentation for details on synchronous replication
support.
