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.
强大的产业优势,是吸引德企扎根的基石。太仓已形成汽车零部件、高端装备、新能源三大德企主导的产业集群,配套企业超千家。博纳环境设备(太仓)有限公司总经理杨鑫华说:“我们在太仓3次增资扩产,因为这里供应链齐全——半径10公里内能找到90%的供应商。”当地的产供链优势不仅降低了企业物流和时间成本,更为德企的发展带来确定性。

更值得警惕的是,民德电子历史募投项目的失速表现,为本次扩产蒙上阴影。2022年公司曾完成5亿元定增,投向碳化硅功率器件研发产业化、高端沟槽型肖特基二极管产能提升两大项目,最终均未达到预期效益。
