與葡萄牙語一樣，我每天要完成四個簡短的任務與測驗；但這次我需要將 12 個完全聽不懂的聲音，配對到 12 個從未見過的物體圖片上。後來我才得知，這些物體與詞彙都不是真實存在的。我口中念出的其實是中文的聲調，而聲調是中文的重要特徵：不同聲調會改變一個詞的意思。

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.
