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.
So to be clear:
Every row in each of the 26 tables has an id of 1?
or
Do you mean the sequences where 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
