What's Changed

New PostgreSQL backend

The new PostgreSQL backend is ready for testing. Enable it with --postgresql-new flag or FERRETDB_POSTGRESQL_NEW=true environment variable. The next FerretDB version will enable it by default.

Docker images changes

Production Docker images use scratch as a base Docker image. The only file present in the image is a FerretDB binary (with root TLS certificates embedded).

arm64 binaries

In addition to linux/arm64 Docker images, we now provide linux/arm64 binaries and .deb / .rpm packages.
