These examples work fine for me in 16.11, and nothing in the
contrib/pgcrypto source code changed between 16.10 and 16.11.
Since pgcrypto depends on OpenSSL, one possible theory is that
your new pgcrypto.so was built against a different version of
OpenSSL than what is installed on your machine. But with no
info about how you did the update, that's only wild speculation.
