57P03

What does this error mean?

Common causes

  • 1Server just restarted and is still in crash recovery
  • 2Standby replica is in read-only recovery mode and DML is being sent to it
  • 3Server is performing point-in-time recovery and not ready for connections

How to fix it

  1. 1Step 1: Wait for the server to finish startup or recovery.
  2. 2Step 2: Verify you are connecting to the primary and not a read-only replica for write operations.
  3. 3Step 3: Use `pg_isready -h <host>` to poll for readiness before starting the pipeline.
  4. 4Step 4: Add startup retry logic to pipelines with exponential backoff.
