Description:
------------
pg_query() should return when an SQL error happens (there are then various function to get the error description.  However in php 5.3.2 (ubuntu lucid) and 5.3.3 (ubuntu maverick), the function doesn't return at all (the php script ends).

Included is a short test script.  As will run on ubuntu as written if you run php cli as the postgres system user, for example:

sudo -u postgres php test_pg_query_not_returning.php

Test script:
---------------
<?php

define ('CONF_DATABASE_NAME', "postgres");
define ('CONF_DATABASE_USER', "postgres");
define ('CONF_DATABASE_PASSWORD', "");
$conn_string = "dbname=".CONF_DATABASE_NAME." user=".CONF_DATABASE_USER." password=".CONF_DATABASE_PASSWORD."\n";
$conn = pg_connect($conn_string) or die("Unable to connect to database, fix this first");

echo "About to execute actual test: \n";
$sql = "SOME INVALID SQL";
$return = pg_query($conn, $sql);

if($return === FALSE) {
        echo "You should see this, but this code is never executed!\n";
}

echo "Even this code is never executed!\n";
?>


Expected result:
----------------
sudo -u postgres php test_pg_query_not_returning.php 
About to execute actual test: 
PHP Warning:  pg_query(): Query failed: ERROR:  syntax error at or near "SOME"
LINE 1: SOME INVALID SQL
        ^
 in /var/www/eureka/html/tests/test_pg_query_not_returning.php on line 11
You should see this, but this code is never executed!
Even this code is never executed!

Actual result:
--------------
sudo -u postgres php test_pg_query_not_returning.php 
About to execute actual test: 
PHP Warning:  pg_query(): Query failed: ERROR:  syntax error at or near "SOME"
LINE 1: SOME INVALID SQL
        ^
 in /var/www/eureka/html/tests/test_pg_query_not_returning.php on line 11

Additional notes:

When the bug occurs, lines like the following are written to the postgresql log:
2010-08-25 17:03:03 EDT LOG:  unexpected EOF on client connection

No errors are reported by apache.
