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.

Fighting False Positives，这一点在旺商聊官方下载中也有详细论述
I wouldn’t necessarily recommend trying to cultivate a guilty displeasure as part of your identity. It’s probably better to focus on positive rather than negative things, though I allow an exception for things that are overabundant and not that good for you, for which snobbery is a totally valid defensive strategy. Similarly, some guilty pleasures are probably better kept a little guilty, if they clash with who you aspire to be. But in general, it’s better to be a confident, self-loving person, and identifying guilty displeasures, so that you can decide what to do with them, seems like a good first step.，更多细节参见体育直播
