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.

As of March 2, the Pokémon TCG Mega Evolution Elite Trainer Box is listed for $88.95 at Walmart (sold by Rares Market, fulfilled by Walmart), which is only $5 shy of the TCGplayer market value and up to $14.91 cheaper than Amazon. Mega Lucario and Mega Gardevoir editions are randomized at Walmart, but it’s still a fantastic deal if you simply want a Mega Evolution booster pack with an ETB’s usual extras.
