PHP5 + PostgreSQL - pg_fetch_row() returning string not array

Question

PHP5 + PostgreSQL (ubuntu 12.04) according to the doco returns an array for pg_fetch_row(). By my test results indicate that it's returning a string, is there some configuration option for this?

$db = openDatabase(<blah>);
$query = "SELECT (id,serial,tag) FROM devices ORDER BY tag ASC";
$result = pg_query($db,$query);
if ($result)
{
    while ($row = pg_fetch_row($result))
        echo "IN: $row[0] - $row[1] - $row[2]";
}

I expect to see

IN: <value> - <value> - <value>

But I get

IN: (<value>,<value>,<value>) - - 

I guess this means pg_fetch_row() is returning a string not an array?!

e.g. the actual run:

IN: (10,7426573,________) - - 
IN: (7,6862,FMUX-TAG) - - 
IN: (9,6914082,L6) - - 

It seems a simple problem, but I can't find an answer. I know I can parse the result, but that's kludgey.

Change SELECT (id,serial,tag) into SELECT id,serial,tag and you're done.
