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.

Most unexpected was Paramount stock’s jump. Wall Street almost always disdains giant acquisitions on the theory that buyers get too excited about big deals and overpay—and indeed, that’s usually what happens. When the deal gets sealed, the buyer’s stock usually drops, but in this case it rose almost 30%. That’s probably because analysts were pleasantly surprised: They had figured Paramount would need to raise its offer from $30 to $32–$34 a share to vanquish Netflix; instead, Paramount offered just $31 and prevailed.，更多细节参见heLLoword翻译官方下载
