Description:
------------
I would love if the pg_fetch_all could take a parameter that would (optionally) allow the indexing of the resultset to be a column value as opposed to 0-based. (as many tables include a primary key/id)

Reproduce code:
---------------
---
From manual page: function.pg-fetch-all
---
I find myself doing the following VERY often:

$res = pg_query("Select * from set_options");
if(!$res) return(0);
$ret = array();
while($r = pg_fetch_assoc($res)){
    $ret[$r['id']] = $r; }
return($ret);


Expected result:
----------------
above produces an associative array indexed on the "id" column. Would like this built into the pg_fetch_all

Actual result:
--------------
see above
