“HostName not verified error message” on SSL connection in postgresql

Question

I created server.crt, server.key and root.crt files on Centos 7 and put the same onto the C:\\Users\\xxxx\\AppData\\Roaming\\postgre

Answer 1

To use the PostgreSQL JDBC driver without server certificate validation, use

sslfactory=org.postgresql.ssl.NonValidatingFactory

as connection parameter or as part of the URL as described in the documentation.

With later versions of the JDBC driver, you have to specify

sslmode=require

because the default value verify-full means that the client wants to check the certificate and identity of the server.
