Description:
------------
pg_trace() does not work. See attatched patch.
I don't know what it means, but it was different
from others which calling php_stream_cast()
(e.g. ext/bz2/bz2.c, ext/gd/gd.c).

I'm not good at English. Sorry.

Reproduce code:
---------------
<?php
        $conn = pg_connect("");
        pg_trace("/home/ishida/trace.log", "w", $conn);
        $res = pg_query($conn, "select 1");
        pg_close($conn);
?>


Expected result:
----------------
$ cat /home/ishida/trace.log
To backend> Msg Q
To backend> 'select 1'
To backend> Msg complete, length 14
From backend> T
From backend (#4)> 33
From backend (#2)> 1
From backend> "?column?"
...

Actual result:
--------------
$ cat /home/ishida/trace.log
