An interesting data point on this is that RedHat's nss_compat_ossl
package doesn't support SSL compression at all
<http://fedoraproject.org/wiki/Nss_compat_ossl>, and it's supposed to be
a path to FIPS 140 compliance:
<http://fedoraproject.org/wiki/FedoraCryptoConsolidation>. The latter
URL, incidentally, contains a lot of good information, and lays out many
of the reasons why I'd like to see us support NSS as an alternative to
OpenSSL, notwithstanding the supposed dirtiness of its API. I imagine
this would be of interest to commercial Postgres vendors also.
