## 48.3. Streaming Replication Protocol Interface

The commands

- `CREATE_REPLICATION_SLOT `slot_name` LOGICAL `output_plugin``

- `DROP_REPLICATION_SLOT `slot_name`` [ `WAIT` ]

- `START_REPLICATION SLOT `slot_name` LOGICAL ...`

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 52.4 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.)
