See <a class="xref" href="functions-admin.html#FUNCTIONS-REPLICATION" title="9.26.6. Replication Functions">Section 9.26.6</a> for detailed documentation on
the SQL-level API for interacting with logical decoding.

Synchronous replication (see <a class="xref" href="warm-standby.html#SYNCHRONOUS-REPLICATION" title="26.2.8. Synchronous Replication">Section 26.2.8</a>) is
only supported on replication slots used over the streaming replication interface. The
function interface and additional, non-core interfaces do not support
synchronous replication.
