Since this is the only thing that match an integer value, try to use
$id =3D $_POST['id'] + 0;
in case there is no id sent. You'll don't get any results [i hope there i=
s
no id==0] but u'll don't have an error on your query.
Because id is integer try not to use *where id=3D'$id'*. Use *where id=3D=
$id*
instead.

print $query; You will get:
UPDATE table SET titulo=3D'somthing',texto=3D'text' WHERE id=3D''

And your pg version is >=3D 7.2, where you can not insert '' string in=20
integer type. cast $id as integer, '".($id+0)."' or intval or others.
