Let me introduce you to what I call the PCM boundary. PCM (Pulse-Code Modulation) is the raw, uncompressed digital audio format that eventually gets sent to your speakers. It’s the terminal endpoint of every audio pipeline, regardless of how aggressively encrypted the source was.
Postgres has its own primitives for things that forges currently build custom infrastructure around. A trigger on the refs table firing NOTIFY means any connected client learns about a push the moment it happens, which is how forges normally end up building a custom webhook polling layer. Multi-tenant repo isolation becomes a database concern through row-level security on the objects and refs tables, and logical replication lets you selectively stream repositories across Postgres instances, a kind of partial mirroring that filesystem-based git can’t do. Commit graph traversal for ancestry queries and merge-base computation falls to recursive CTEs, and pg_trgm indexes on blob content give you substring search across all repositories without standing up a separate search index.

是各自为政，搞保护主义、本位主义，还是胸怀“国之大者”、树牢全局思维？
鲍师傅只有100多家店，却坚持80%的制作面积、20%的销售面积，靠新鲜现做实现高复购；太二重新回归活鱼、活虾、鲜牛肉、鲜鸡、鲜猪肉，核心就是回归新鲜本质；我们打造的椿芽鲜牛肉杭州拌川，用鲜切牛肉改造传统杭椒牛柳，70平米的门店，月营收稳定在95万，这就是新鲜带来的价值；有家酸菜鱼坚持“吃活鱼，选有家”的定位，不盲目扩张、不做加盟，靠直营稳步发展，这都是值得借鉴的案例。
