It correctly skipped tests involving SSL in the server when SSL support was not compiled in, but even when SSL is not enabled in the server and the connection is established without SSL, libpq behaves differently in many of the test scenarios when libpq is compiled without SSL support. For example, with sslmode=prefer, if libpq is compiled with SSL support it will attempt to use SSL, but without SSL support it will try authenticating in plaintext mode directly. The expected test output didn't take that into account. Discussion: https://www.postgresql.org/message-id/CA%2BhUKG%2BHRTtB%2Bx%2BKKKj_cfX6sNhbeGuqmGxjGMwdVPG7YGFP8w@mail.gmail.com
