feature request - allow to set option is_called for setval

Hi,
I just noticed pgAdmin cannot set value of sequence to start with 1 because
generates SQL like this:
SELECT setval('"MySchema"."MySequence"', 1, true);

it is not possible to set "is_called" option of setval to false.
According to doc (
http://www.postgresql.org/docs/9.1/static/functions-sequence.html):
* "If it is set to false, the next nextval will return exactly the
specified value, and sequence advancement commences with the following
nextval"*

so, please add checkbox in sequence properties to allow to modify this
switch.

thanks & regards,
Bartek
