Fails against pgbouncer

[adunstan]

In this example I have pgbouncer running on port 6932. I can connect using psql on SSL mode, but this script fails:

andrew@ad-c7:test $ psql "sslmode=verify-full host=localhost port=6932 dbname=workdb sslcert=myCA/curly.crt sslkey=myCA/curly.key sslrootcert=myCA/root.crt user=curly"
psql (11beta3 (2ndQPG 11.0r1.2))
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES128-GCM-SHA256, bits: 128, compression: off)
Type "help" for help.

workdb=> \q
andrew@ad-c7:test $ python postgres_get_server_cert.py localhost:6932 
Something failed while fetching certificate: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:579)

Thanks for the heads up. I'm not spending any time on maintaining this script right now, but I'll accept a PR if you figure out why it doesn't work. I'd start by trying to figure out what's going on at the TLS level, what cipher suites and protocols are allowed by the server and what does the client try to connect with.
