Currently only version 1 is supported. publication_names Comma separated

ssl_max_protocol_version (enum) Sets the maximum SSL/TLS protocol version to use. Valid values are as for ssl_min_proto- col_version, with addition of an empty string, which allows any protocol version. The default is remote_apply. The write-ahead log is streamed over a regular PostgreSQL connection and uses the replication proto- col. The connection must be made with a user having REPLICATION permissions (see Section 22.2) or Replication Parameters The logical replication START_REPLICATION command accepts following parameters: proto_version Protocol version. Currently versions 1 and 2 are supported. The version 2 is supported only
