Yes, I think so. pgcrypto uses openssl and gpg internally, so using those tools should work.
I know that pgp_sym_encrypt and pgp_sym_decrypt interoperates well with "outside the database" gpg, although dealing with armoring and de-armoring as well as text mode or binary mode is a bit of a bother until you get used to it.
But he seems to be asking about the "F.25.4. Raw Encryption Functions". I wouldn't want to reassure him that it would be easy to make those work outside the database, without having seen it done. But it should of course be possible to make it work, even if that means rearranging the code of pgcrypto and compiling into something that is standalone.
