Bug Type:         Bug
Bug description:SELECT COUNT() returns string, not int.

Description:
------------
---
From manual page: http://www.php.net/pdostatement.fetchcolumn
---
With this SQL statement

SELECT count(*) FROM my_table;

fetchColumn() returns an INTEGER with Postgres and a STRING with Sqlite.
That is, if there is one row in the table, Postgres returns (int)1 and
Sqlite returns '1'.

Note that

SELECT TYPEOF(b) FROM ( select count(*) as b from my_table) a;

produces integer in Sqlite.

Test script:
---------------
http://pastebin.com/arGpxjm7

Expected result:
----------------
I expect both Postgres and Sqlite to return an integer type from
fetchColumn() in both cases, since that is what the database claims it
is returning.  That is, I expect this result from my test script:

Postgres: int(1)
Sqlite3:  int(1)

Actual result:
--------------
Postgres: int(1)
Sqlite3:  string(1) "1"
