Pgpool-II handles connection between client and Pgpool-II, and between Pgpool-II and PostgreSQL separately. i.e. it is possible to establish SSL connection between client and Pgpool-II while the connection between Pgpool-II and PostgreSQL is established without SSL depending the configuration of Pgpool-II and PostgreSQL (for example, if Pgpool-II is configured to connect to PostgreSQL using Unix-socket, SSL will be disabled between Pgpool-II and PostgreSQL as you said). I think the error suggests that there's something wrong with Pgpool-II SSL configuration. For example, if the pass to ssl key is wrong, you see something like below in the pgpool log while pgpool is starting up: 2019-12-11 08:53:23: pid 8506: WARNING: could not access private key file "/usr/local/etc/server.keyk": No such file or directory > Seems like > something you should discuss with the pgpool people. True. The issue is almost nothing to do with PostgreSQL. I recommend to discuss in the pgpool mailing list: https://www.pgpool.net/mailman/listinfo/pgpool-general BTW, pgpool 3.7.5 is pretty old (released in 2018). The latest one in 3.7.x series is 3.7.12. -- Tatsuo Ishii SRA OSS, Inc. Japan English: http://www.sraoss.co.jp/index_en.php Japanese:http://www.sraoss.co.jp
