## 49.3. 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 53.4](protocol-replication.html) for details on these commands.

 The command [pg\_recvlogical](app-pgrecvlogical.html) can be used to control logical decoding over a streaming replication connection. (It uses these commands internally.)
