DBD::Pg 1.00 won't allow me to use the following
the code anymore

----------
$s=$dbh->prepare('select * from table');
$s->execute or die $dbh->errstr;
while(my @a=$s->fetchrow_array())
    {
    ... do something
    }
while(my @a=$s->fetchrow_array())
    {
    .. do something else
    }
-----------

It was fine before with 0.9?

Now I need another execute statement before
the second while statement.

Thanks
