Driver does not respect context during connection

[Darida]

Default driver do not implements DriverContext:

// Driver is the Postgres database driver.
type Driver struct{}

// Open opens a new connection to the database. name is a connection string.
// Most users should only use it through database/sql package from the standard
// library.
func (d Driver) Open(name string) (driver.Conn, error) {
	return Open(name)
}

func init() {
	sql.Register("postgres", &Driver{})
}

as a result, when src/database/sql/sql.go do

ci, err := db.connector.Connect(ctx)

it uses default connector which ignore context:

func Open(driverName, dataSourceName string) (*DB, error) {
	driversMu.RLock()
	driveri, ok := drivers[driverName]
	driversMu.RUnlock()
	if !ok {
		return nil, fmt.Errorf("sql: unknown driver %q (forgotten import?)", driverName)
	}

	if driverCtx, ok := driveri.(driver.DriverContext); ok {
		connector, err := driverCtx.OpenConnector(dataSourceName)
		if err != nil {
			return nil, err
		}
		return OpenDB(connector), nil
	}

	return OpenDB(dsnConnector{dsn: dataSourceName, driver: driveri}), nil
}

It results in connection hanging indefinitelly and leaking ports if database become unreachable during connection.
