pgit: I Imported the Linux Kernel into PostgreSQL

pgit ingested 20 years of the Linux kernel: 1.43M commits, 24.4M file versions. The dataset lives in PostgreSQL with pg-xpatch - 2.7GB on disk.

A 2-hour import on a 24-core EPYC built a queryable SQL DB. Most delta-decompressed queries return in <10s. No preprocessing required.
