If I got a single ounce of feedback on them, sure. The only responses
have involved the licence so far. I won't deny some of the other
features were also controversial.

Please read the OpenSSL-GPL FAQ. They themselves acknowledge it's a
problem, but claim they fall under the "operating system exception",
which is fine for everyone except the distributor of the operating


They recommend that if you want to use OpenSSL, use a licence other
than the GPL.

Wikipedia also has more information about this.

The original authors have been asked and apparently can't be found or
don't care. I strongly suggest you read the openssl archives before
opening this can of worms. Note the authors involved are no longer part
of OpenSSL, they have another SSL library, so they're probably not
inclined to be nice.

AIUI all compiled distributions of postgresql using openssl do actually
include such. For example the Windows Installer.

We're in the bizarre situation were both Debian and the OpenSSL groups
beleive it is a problem, and postgresql does not. Quite odd.
