How do I use prepared statements using database/sql with Postgres?

Prepared statements in Go allow you to execute SQL queries efficiently and securely by reusing query plans and preventing SQL injection attacks. Using the `database/sql` package with PostgreSQL, you can easily integrate prepared statements into your application. Here's a simple example of how to use prepared statements with the `database/sql` package in Go.


        package main

        import (
            "database/sql"
            "log"

            _ "github.com/lib/pq"
        )

        func main() {
            // Connect to the PostgreSQL database
            connStr := "user=username dbname=mydb sslmode=disable"
            db, err := sql.Open("postgres", connStr)
            if err != nil {
                log.Fatal(err)
            }
            defer db.Close()

            // Prepare a statement for execution
            stmt, err := db.Prepare("INSERT INTO users(name, age) VALUES($1, $2)")
            if err != nil {
                log.Fatal(err)
            }
            defer stmt.Close()

            // Execute the prepared statement with desired values
            _, err = stmt.Exec("Alice", 30)
            if err != nil {
                log.Fatal(err)
            }

            log.Println("User added successfully!")
        }
