From Mike's comments on Reddit[0]

pgsodium 2.0.0 is a postgres extension that uses the libsodium library to provide high-performance, modern cryptography support for PostgreSQL 10+.

2.0.0 includes a ton of new feature and a few bug-fixes:

* Support for XChaCha20-SIV[2] deterministic nonce-free encryption

* Support for SignCryption[3] Sign & Encrypt identity verification

* Key id support for HMACSHA 512/256, generichash, and shorthash

* Support for low level XChaCha20 streaming[4]

* More tests, docs, and small bug fixes in argument parsing

* In-memory key now protected with sodium_malloc[5]
