Over the past year or two, I’ve seen many organizations, large and small, implement passkeys (which is great, thank you!) and use the PRF (Pseudo-Random Function) extension to derive keys to protect user data, typically to support end-to-end encryption (including backups).
“Wasm + JS glue”: A WebAssembly function which reads the change list in a loop, and then asks JS glue code to apply each change individually. This is the performance of WebAssembly today.

Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.
