Every time I try to insert I get the error: docking_dev=# INSERT INTO "chinese_price_infos" ("item_code", "price_cents", "unit", "description", "company_id", "created_at", "updated_at") VALUES ('01GS10001', 6000, 'Lift', 'Shore Crane Rental', '9ae3f8b8-8f3f-491c-918a-efd8f5100a5e', '2019-05-06 10:49:03.894725', '2019-05-06 10:49:03.894725'); ERROR: duplicate key value violates unique constraint "chinese_price_infos_pkey" DETAIL: Key (id)=(71165) already exists. docking_dev=# INSERT INTO "chinese_price_infos" ("item_code", "price_cents", "unit", "description", "company_id", "created_at", "updated_at") VALUES ('01GS10001', 6000, 'Lift', 'Shore Crane Rental', '9ae3f8b8-8f3f-491c-918a-efd8f5100a5e', '2019-05-06 10:49:03.894725', '2019-05-06 10:49:03.894725'); ERROR: duplicate key value violates unique constraint "chinese_price_infos_pkey" DETAIL: Key (id)=(71166) already exists. Then I found: docking_dev=# SELECT MAX(id) FROM chinese_price_infos; max -------- 128520 (1 row) docking_dev=# SELECT nextval('chinese_price_infos_id_seq'); nextval --------- 71164 (1 row) Not sure how it is out of sync. How can I fix this permanently. I ran vacuum analyze verbose; still same error. Thanks, Arup Rakshit ar@xxxxxxx
