45.3. Streaming Replication Protocol Interface
The commands
- CREATE_REPLICATION_SLOT- slot_nameLOGICAL- output_plugin
- DROP_REPLICATION_SLOT- slot_name
- START_REPLICATION SLOT- slot_nameLOGICAL ...
are used to create, drop, and stream changes from a replication slot, respectively. These commands are only available over a replication connection; they cannot be used via SQL. See Section 49.3 for details on these commands.
The command pg_recvlogical can be used to control logical decoding over a streaming replication connection. (It uses these commands internally.)
