If the update changes row by row, each of a time, then it might break. trivial differences in description or coordinate fields), you can use DISTINCT ON: A common coding strategy is to have multiple application servers attempt to insert the same data into the same table at the same time and rely on the database unique constraint to prevent duplication. 1. Code language: SQL (Structured Query Language) (sql) Creating a UNIQUE constraint on multiple columns. If you have a sequencer on the field (like with a serial column type), it is likely out of sync with the table because you have done an insert and supplied a value (rather than letting the "default" mechanism handle it by getting the nextval from the sequencer).

At a later point some records are inserted without id and they fail with the error: Error: duplicate key value violates unique constraint. Modified 7 years, 9 months ago. That likely means that the primary key sequence in the table you're working with has somehow become out of sync, likely because of a mass import process (or something along those lines). Hopefully, these insights will help At a later point some records are inserted without id and they fail with the error: Error: duplicate key value violates unique constraint. Apparently the id got defined as a sequence: Each failed insert increases the pointer in the sequence till it increments to a value that no longer exists and the queries succeed. e (I was I'm using psql in my Laravel App. But first to check if values are out of sync, we can use below queries.
