I don't know what version of Pgpool-II you are using, and trying to migrate to but if you are using Pgpool-II dedicated extensions, be sure to upgrade them as well. For more information regarding Pgpool-II version up, please refer to the release notes sections. https://pgpool.net/mediawiki/index.php/Documentation Best regards, -- Tatsuo Ishii SRA OSS, Inc.
