巴爾金指出，北京認為特朗普（Donald Trump，川普）對歐洲咄咄逼人的姿態增強了自己對歐洲各國的影響力，但同時，在中國經濟問題艱困、美國市場仍對中國商品實施管制之際，北京也需要歐洲市場。因此北京盼望德國總理的訪問展現中德夥伴關係形象，同時將自己塑造成日益脆弱的地緣政治格局中穩定的保障者。。safew官方版本下载对此有专业解读
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.
