pgcrypto works now as well, thanks!

Otoh these symbols are strictly version-dependant on OpenSSL, it's not
like one of the symbols would appear or disappear for other reasons
(like different TLS implementation, or different operating system).

Once we decide (in 10 years?) that the minimum supported OpenSSL
version is >= 1.1, we can just drop the version checks. If these are
converted to feature tests now, it will be much harder to remember at
which point they can be dropped.
