plperl and plpython can be annoying to require if you have strong
security requirements as these are untrusted languages, but I don't
completely agree with this argument because pgcrypto gives the option
to use SHA1 with digest(), and this one is fine to have even in
environments under STIG or equally-constrained environments.

Consistency with the existing in-core SQL functions for cryptohashes
and the possibility to not need pgcrypto are my only arguments at
hand.
