      1 # pgconn
      2 
      3 Package pgconn is a low-level PostgreSQL database driver. It operates at nearly the same level as the C library libpq.
      4 It is primarily intended to serve as the foundation for higher level libraries such as https://github.com/jackc/pgx.
      5 Applications should handle normal queries with a higher level library and only use pgconn directly when required for
      6 low-level access to PostgreSQL functionality.
      7 
      8 ## Example Usage
      9 
     10 ```go
     11 pgConn, err := pgconn.Connect(context.Background(), os.Getenv("DATABASE_URL"))
     12 if err != nil {
     13 	log.Fatalln("pgconn failed to connect:", err)
     14 }
     15 defer pgConn.Close(context.Background())
     16 
     17 result := pgConn.ExecParams(context.Background(), "SELECT email FROM users WHERE id=$1", [][]byte{[]byte("123")}, nil, nil, nil)
     18 for result.NextRow() {
     19 	fmt.Println("User 123 has email:", string(result.Values()[0]))
     20 }
     21 _, err = result.Close()
     22 if err != nil {
     23 	log.Fatalln("failed reading result:", err)
     24 }
     25 ```
