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.
党性是党员干部立身、立业、立言、立德的基石。只有党性坚强、摒弃私心杂念，才能确保在实践中准确、自觉地运用马克思主义立场观点方法，才能保证政绩观不出偏差。本位主义、好大喜功、弄虚作假、推脱责任……几种政绩观错位的表现，说到底是认识上出现了偏差，根子在于背离了党性、丢掉了宗旨、抛弃了信念。
