Description:
------------
I want to add read event to pg_socket with event extension both don't accept resource of pg_socket but stream_select works well

For simplicity I write test script with well known library called reactphp/event-loop


if you run test script using event extension , this warning shown and there is no read event 

PHP Warning:  Event::add(): Epoll ADD(1) on fd 30584288 failed. Old events were 0; read change was 1 (add); write change was 0 (none); close change was 0 (none): Bad file descriptor in vendor/react/event-loop/src/ExtEventLoop.php on line 259
PHP Warning:  Event::add(): Failed adding event in vendor/react/event-loop/src/ExtEventLoop.php on line 259



Test script:
---------------
$loop = React\EventLoop\Factory::create();
$connection = pg_connect("host=localhost port=5432 dbname=mary");
$socket = pg_socket($connection);
$loop->addReadStream($socket , function (){
  echo "READ EVENT\n";
});

pg_send_query($connection , "select * from authors;");

Expected result:
----------------
PHP Warning:  Event::add(): Epoll ADD(1) on fd 30584288 failed. Old events were 0; read change was 1 (add); write change was 0 (none); close change was 0 (none): Bad file descriptor in vendor/react/event-loop/src/ExtEventLoop.php on line 259
PHP Warning:  Event::add(): Failed adding event in vendor/react/event-loop/src/ExtEventLoop.php on line 259

If this is still an issue with any of the actively supported PHP
versions[1] and the latest event package (3.0.5), please provide a
self contained reproduce script (not using any PHP libraries or
frameworks).
