Hi All, We have a PostgreSQL database. There are 26 tables and we use serial type as primary key. We had a insert error as “duplicate key value violates unique constraint, DETAIL: Key (id)=(1) already exists.” one weeks ago. I checked and found
all tables’ id were reset to 1. I checked database log and did not find any useful information. I am not sure why this happen. The only script which connect to this database is a Python script and only do normal insert/update/delete actions.
Please give me some suggestions if you happen to know something about this issue. I appreciate any feedback you might have. I am very new to PostgreSQL and this mail list. Please let me know if I did not something wrong. Thank you. Regards, Max |
