Database

To implement the repository pattern in Golang for PostgreSQL, abstract database access logic using interfaces and the `pgx` driver, ensuring code organization and testability. This approach prevents global DB connections and improves maintainability.

The best way to generate type-safe SQL queries in Golang is using `sqlc`. It compiles SQL into native Go code, reducing runtime errors while adhering to the standard of preferring raw SQL or query builders over ORMs.

You should avoid ORMs in Golang database interaction because raw SQL and builders provide better performance and control. Preferring raw SQL avoids ORM abstraction leaks and aligns with Go's explicit error handling paradigms.

Configure connection pooling in Golang with `pgx` by tuning pool parameters like maximum connections and idle timeouts. Proper connection tuning optimizes performance and prevents resource exhaustion in microservices.

Common database connection anti-patterns in Go include using global DB connections and ignoring context. These practices lead to unmanageable state and unresponsive requests, making connection pooling and context-aware interfaces essential.

Yes, implementing the repository pattern for PostgreSQL in Golang specifies the `jackc/pgx` driver. It provides robust connection pooling and context-aware execution, ensuring efficient database interaction without ORM overhead.
