If the client supports ALPN but tries to use some other protocol, like HTTPS, reject the connection in the server. That is surely a confusion of some sort. Furthermore, the ALPN RFC 7301 says: > In the event that the server supports no protocols that the client > advertises, then the server SHALL respond with a fatal > "no_application_protocol" alert. This commit makes the server follow that advice. In the client, specifically check for the OpenSSL error code for the "no_application_protocol" alert. Otherwise you got a cryptic "SSL error: SSL error code 167773280" error if you tried to connect to a non-PostgreSQL server that rejects the connection with "no_application_protocol". ERR_reason_error_string() returns NULL for that code, which frankly seems like an OpenSSL bug to me, but we can easily print a better message ourselves.
