Set libpq sslcompression to off by default
Since SSL compression is no longer recommended, turn the default in
libpq from on to off.
OpenSSL 1.1.0 and many distribution packages already turn compression
off by default, so such a server won't accept compression anyway. So
this will mainly affect users of older OpenSSL installations.
Also update the documentation to make clear that this setting is no
longer recommended.
