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.,这一点在搜狗输入法2026中也有详细论述

If they have time, astronauts and cosmonauts will look to plug the leak or close the hatch to the leaking section of the station. (That is how they dealt with a minor leak in the station’s PrK module for a number of years, and it basically worked.) Remember, though, that this is the worst-case scenario, and our crew will run into a hard deadline. Once pressure falls to around 490 mm Hg, NASA says, critical systems risk breaking down. Astronauts could suffer hypoxia, oxygen deprivation so debilitating they could become delirious. It will be a heart-wrenching call, but if nothing else can be done, the crew will need to go to their crew vehicles and leave the ISS.
