PostgreSQL transaction fails with deadlock detected error in psycopg2 and Django
  • Applications using Django with PostgreSQL and psycopg2 may encounter `deadlock detected` errors under concurrent write-heavy workloads.
  • PostgreSQL raises this error when two or more transactions block each other cyclically while waiting for locks, and one must be aborted.
  • Django surfaces this as an `OperationalError`, and the affected transaction is rolled back.
