First do something like below to get the name of the sequence associated with
the serial type:
test(5432)aklaver=>\d serial_test
Table "public.serial_test"
Column | Type | Modifiers
--------+---------+----------------------------------------------------------
id | integer | not null default nextval('serial_test_id_seq'::regclass)
fld_1 | text |
Then go here:
http://www.postgresql.org/docs/9.0/interactive/functions-sequence.html
and use one of the setval() functions to set the sequence start to 1000.
Note: This is assuming the table is empty and you will not have any id
collisions.
