But if you use the pgx/v5 sql package then you can specify a some struct instead of default 当设置为 pgx/v5 时，SQLC会生成专门针对pgx驱动的接口，直接使用pgx特有的类型（如CommandTag、Rows等） 当设置为 database/sql 时，才会生成与标准库兼容的接口 解决方案 Queries to structs. 18. Stay tuned for more Or alternatively, what additional imports do I need? I'd like to start using Postgres as my main DBMS for some development I am doing, and my research suggests that pgx is the database If you don't use pgx, you could relatively easily intercept the queries as they're being sent to the database by implementing a DBTX that logs and then sends them on to the database.
