47.3. Streaming Replication Protocol Interface (original) (raw)

This documentation is for an unsupported version of PostgreSQL.
You may want to view the same page for thecurrent version, or one of the other supported versions listed above instead.

The commands

• CREATE_REPLICATION_SLOT _`slotname`_ LOGICAL _`outputplugin`_
• DROP_REPLICATION_SLOT _`slotname`_ [ WAIT ]
• START_REPLICATION SLOT _`slotname`_ 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 54.4 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.)
