tidak dapat menyisipkan baris pada id, tetapi baris tidak ada

Inilah masalah aneh yang saya hadapi. Saya mencoba memasukkan data menggunakan kueri berikut

insert into product_product 
(id, product_tmpl_id, make_equip, model_equip, name_template, serial_num_equip, location_equip, issue_date_equip, issue_to_equip, remarks_equip, pr, ch,  categ_id,valuation) 
values (700,700,'Nikon','Action 10x50 Lookout','Nikon Action 10x50 Lookout','671386','40 Wall St.','5/13/2004 12:00:00 AM','','OM''s OFFICE',62,72,502,'manual periodic');

Saya mendapatkan kesalahan:

ERROR:  duplicate key value violates unique constraint "product_product_pkey"
DETAIL:  Key (id)=(700) already exists.

********** Error **********

ERROR: duplicate key value violates unique constraint "product_product_pkey"
SQL state: 23505
Detail: Key (id)=(700) already exists.

Saya menjalankan kueri pemilihan pada catatan itu seperti ini:

select * from product_product
where id=700

Ini mengembalikan kolom tanpa data (data termasuk id juga)

Saya mencoba menjalankan permintaan pembaruan seperti ini:

update product_product set 
                        product_tmpl_id=700,
                        make_equip='Nikon', 
                        model_equip='Action 10x50 Lookout', 
                        name_template='Nikon Action 10x50 Lookout', 
                        serial_num_equip='671386', 
                        location_equip='40 Wall St.', 
                        issue_date_equip='5/13/2004 12:00:00 AM', 
                        issue_to_equip='',
                        remarks_equip='OM''s OFFICE', 
                        pr=62, 
                        ch=72, 
                        categ_id=502,valuation='manual periodic' where id=700;

hasilnya adalah:

Query returned successfully: 0 rows affected, 1 ms execution time.

saya mencoba menghapus kueri juga tetapi keluaran yang sama.

Juga tampilkan semua data tidak seperti id 700.

Saya tidak tahu mengapa ini terjadi.

Saya mengindeks dan menyedot meja saya dari pemeliharaan tetapi hasilnya sama.

Tolong beritahu saya apa yang salah dengan itu.

Terima kasih

Edit

di sini adalah tabel buat saya

Saya memiliki sekitar 200 kolom, jadi saya telah menghapusnya dari sini ....

Gambar baris terakhir dalam product_product adalah

ID kolom didefinisikan sebagai SERIAL yang mirip dengan properti AUTO_INCREMENT yang didukung oleh beberapa database lain. Jadi, Anda harus menghilangkannya dalam pernyataan INSERT atau menggunakan kata kunci DEFAULT dan id baru akan dihasilkan secara otomatis.

Lihat bagian 8.1.4. Jenis Serial: http://www.postgresql.org/docs/9.3/static/datatype-numeric.html
