Description:
------------
Using pg_insert() with a data array that offers a long integer (1125522000) for a table field which was supposed to be of type 'date'. PHP crashes instantly.

However, I cannot seem to reproduce this except in a rather complex closed source application.

Reproduce code:
---------------
$data = array(
 'project_id'=>122,
 'transaction_model_id' => 2,
 'status' => 'FINAL',
 'date_created' => 1125522000, //should be string in "date" format
 'i18n_id' => 339451,
 'unique_id' => 497263,
);
$res = pg_insert(DB,'table_name',$data);
echo 'it never gets here';

Expected result:
----------------
pg_insert() apparently doesn't produce any log message of any kind, ever. But I at least expected it to return false instead of crashing.

It's worth noting that 5.0.5 doesn't have this problem. In 5.0.5, pg_insert() returns false and the error can be picked up by the rest of the code.

However, 4.4.0 and 4.3.11 do have the problem.

Actual result:
--------------
Crash. I will try to provide a backtrace.
