Bug description:pg_fetch return space char on empty field
Description:
------------
pg_fetch_* returns space string (e.g. ' ') when returning a
empty sting ''
Postgres is
returning an empty string and pg_fetch is changing the return
value.
Empty string is only return if the result is
caste as a varchar in the sql

e.g."SELECT test_thing::varchar".
Test script:
---------------
//In DB
CREATE TABLE test ( test_thing VARCHAR(5) NOT NULL
DEFAULT '');
INSERT INTO test VALUES
('');

//code
$testing
= pg_query($db_conn,"SELECT test_thing FROM test WHERE
test_thing='');
print_r(pg_fetch_all($testing));
print
'testing'.pg_fetch_result($testing,0,0).'this';
Expected result:
----------------
array(1) {
[0]=
 array(1)
{

['test_thing']=
 string(0)
''
}
}

testingthis

Actual result:
--------------
array(1) {
[0]=
 array(1)
{

['test_thing']=
 string(1)
'
'
}
}
