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.
2012年正是夜总会“还能维持体面”的尾声。香港夜总会的衰落是一个渐进的过程，是多重结构性力量叠加的结果。1997年亚洲金融风暴、2008年全球金融危机之后，“一掷千金”的风气不再；江湖社会向现代法治商业社会转型，黑帮势力消退；狗仔队的发力使达官贵人不再愿意公开现身；澳门及其他地区分流了高端夜间消费；更具决定性的变化来自技术——智能手机的普及使客人与从业者可以直接联络，夜总会赖以存在的“中介结构”被击穿。一个建立在信息不对称、关系调度与人情往来之上的行业，在透明化与科技化面前迅速失效。
