The pgsql driver is surely affected. The oci driver might be affected,
although I don't have enough experience with it to verify.

From what I can see the problem is that the get_col API can set value
either to a (php_stream *) or a (char *). The check on value[0] was
added to fix http://bugs.php.net/bug.php?id=46274, to prevent the stream
related code to be run when an empty string is returned by the driver.

As you've already seen my proposal was to an is_stream parameter to the
get_col API to make sure PDO knows what it's expected to handle.
