how to emulate “insert ignore” and “on duplicate key update” (sql merge) with postgresql?

问题 Some SQL servers have a feature where INSERT is skipped if it would violate a primary/unique key constraint. For instance, MySQL has INSERT IGNORE . What's the best way to emulate INSERT IGNORE and ON DUPLICATE KEY UPDATE with PostgreSQL? 回答1: Try to do an UPDATE. If it doesn't modify any row that means it didn't exist, so do an insert. Obviously, you do this inside a transaction. You can of course wrap this in a function if you don't want to put the extra code on the client side. You also

问题 I have a website, say example.com. Couldflare is set to cache everything on *example.com/* If I add another rule: *nope.example.com/* And set it to bypass cache, what will cloudflare do with the conflicting page rules? 回答1: According to Source A; Page Rules are applied in the order that they are listed.
