ALTER SEQUENCE uses the sequence name, not the table name. Also,
use RESTART WITH to set the sequence's current value. Example:
test=> CREATE TABLE users (id serial PRIMARY KEY, username text);
NOTICE: CREATE TABLE will create implicit sequence "users_id_seq" for "serial" column "users.id"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "users_pkey" for table "users"
CREATE TABLE
test=> ALTER SEQUENCE users_id_seq RESTART WITH 10000;
ALTER SEQUENCE
test=> INSERT INTO users (username) VALUES ('Alice');
INSERT 2592322 1
test=> INSERT INTO users (username) VALUES ('Bob');
INSERT 2592323 1
test=> SELECT * FROM users;
id | username
-------+----------
10000 | Alice
10001 | Bob
