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.
加拿大人格雷格在广州旅居多年，日前到天津旅行。走进茶馆听相声，徜徉杨柳青古镇欣赏年画，跟着“泥人张”匠人体验泥塑制作……“这些民俗风情、传统技艺，无不彰显出中华优秀传统文化的深厚底蕴。”格雷格说。
