PostgreSQL concurrent row update

原文 2021-10-20 19:51:02 1 1 postgresql

Can someone say how PostgreSQL behaves when i'm trying to update same row but different fields at the same time (concurrently)? What transaction level it's using

When you update a row, the whole row is locked until the end of the database transaction. So the first update will block the second one, even if they modify different columns. This is independent of the transaction isolation level.
