Description:
------------
pgsql modules returns all non-null values as String type data instead of corresponding php datatype when applicable. PDO is not affected though. 

Test script:
---------------
# CREATE TABLE netusers (id bigserial NOT NULL, firstname character varying NOT NULL, middlename character varying NOT NULL DEFAULT ''::character varying, lastname character varying NOT NULL DEFAULT ''::character varying, company_id integer NOT NULL DEFAULT 0, department_id integer NOT NULL DEFAULT 0, connect_date date NOT NULL DEFAULT now(), disconnect_date date, login character varying NOT NULL DEFAULT ''::character varying, password character varying NOT NULL DEFAULT ''::character varying, email text NOT NULL DEFAULT ''::character varying, email_alias text NOT NULL DEFAULT ''::character varying, computer character varying NOT NULL DEFAULT ''::character varying, ipaddr bigint NOT NULL DEFAULT 0, macaddr bigint NOT NULL DEFAULT 0, inet_date date, phone_local text NOT NULL DEFAULT ''::text, phone_global text NOT NULL DEFAULT ''::text, comment text, cable_id bigint NOT NULL DEFAULT 0, CONSTRAINT netusers_pk PRIMARY KEY (id )) WITH (OIDS=FALSE);
# Put a row into that table with some random (but according to columns' datatype) data
<?php
$dsn = 'pgsql:host=host;port=5432;dbname=testdb';
$username = 'test';
$password = 'testpw';

$conn = new PDO($dsn, $username, $password);
$stmt = $conn->query('select * from netusers');
$o = $stmt->fetchObject();
//This gets appropriate datatypes for all non-null fields (int for int, string for string etc... Except (hell yeah!) arrays)
var_dump($o);
//*************************
$conn2 = pg_connect("host=host port=5432 dbname=testdb user=test password=testpw");
$stmt2 = pg_query($conn2, "SELECT * FROM netusers");
$o2 = pg_fetch_object($stmt2);
//This gets an object with every non-null property having datatype string
var_dump($o2);


Expected result:
----------------
# This is the PDO output part of the test script
object(stdClass)#3 (20) {
  ["id"]=>
  int(0)
  ["firstname"]=>
  string(3) "asd"
  ["middlename"]=>
  string(7) "dasfsdf"
  ["lastname"]=>
  string(8) "sdafdsdf"
  ["company_id"]=>
  int(0)
  ["department_id"]=>
  int(0)
  ["connect_date"]=>
  string(10) "2011-10-28"
  ["disconnect_date"]=>
  NULL
  ["login"]=>
  string(6) "asfdfg"
  ["password"]=>
  string(6) "dfsdfg"
  ["email"]=>
  string(22) "cvbcvbcvb@xcvxcvxcv.as"
  ["email_alias"]=>
  string(0) ""
  ["computer"]=>
  string(5) "sdasd"
  ["ipaddr"]=>
  int(0)
  ["macaddr"]=>
  int(0)
  ["inet_date"]=>
  NULL
  ["phone_local"]=>
  string(6) "234234"
  ["phone_global"]=>
  string(0) ""
  ["comment"]=>
  string(14) "svsdfgsdfgsdfg"
  ["cable_id"]=>
  int(0)
}
