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.

在集市上买了条罩衣围裙，15元。每次做完饭摘围裙时，像从手术台下来。以前，我扎那种半身围裙。这种带袖围裙，我只在婆婆家穿过一回。我娘家的女性很奇怪，除了我，她们都不爱扎围裙。这条围裙我超爱，有时一整天都穿着它，出门都不想脱。，更多细节参见51吃瓜
