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.
Sign-ups to play an alpha of Stage Tour will open soon, and RedOctane plans to "kick off closed alpha testing late spring/early summer." We're long past the peak popularity of games like Guitar Hero, but rhythm and music games never went away. Players have had Clone Hero and more official experiences like Fortnite Festival to get their Guitar Hero or Rock Band fix, but Stage Tour could be a more than welcome third option when it launches later this year.
