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.

“海信+东芝”的双品牌战略，让海信的技术优势和东芝的品牌积淀都得到了极大限度的发挥，尤其在日本本土的彩电市场，东芝子品牌REGZA销量已连续四年登顶。销量的回暖也让东芝的财务状况得以改善，根据海信视像2019年半年报，东芝映像在上半年还是亏损状态。到了海信视像2020年年报披露，东芝映像已经营大幅改善，并实现扭亏为盈。
