Content-level diffs, three-way merge, and blame stay in libgit2 rather than being reimplemented in SQL, since libgit2 already has that support and works against the Postgres backends through cgo bindings. The Forgejo fork would be “replace modules/git with libgit2 backed by Postgres” rather than “replace modules/git with raw SQL,” because the read-side queries only cover the simple cases and anything involving content comparison or graph algorithms still needs libgit2 doing the work with Postgres as its storage layer. That’s a meaningful dependency to carry, though libgit2 is well-maintained and already used in production by the Rust ecosystem and various GUI clients. SQL implementations of some of this using recursive CTEs would be interesting to try eventually but aren’t needed to get a working forge. The remaining missing piece is the server-side pack protocol: the remote helper covers the client side, but a Forgejo integration also needs a server that speaks upload-pack and receive-pack against Postgres, either through libgit2’s transport layer or a Go implementation that queries the objects table directly.
她时常提起自己的母亲、我的外婆有多么重视围炉，会为此连续几个清晨早起赶去菜市场，只为买到最新鲜的食材、最紧俏的部位。外婆有一手好厨艺，我妈记忆中，在物资匮乏的儿时，每年最期待的就是这一顿盛宴。
