PostgreSQL 57P01: admin_shutdown
Evidence linked to this decision
View source: PostgreSQL 18 Appendix A: Error CodesRisk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
SQLSTATE 57P01 (admin_shutdown) means the session ended because PostgreSQL is shutting down by administrative action. Diagnose the named condition before retrying.
Safety first
Safe checks you can perform
- Correlate the shutdown with the change timeline
What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Correlate the shutdown with the change timeline
Compare the timestamp with deployment, maintenance, failover and PostgreSQL logs. If planned, wait for the correct primary to pass readiness and reconnect with bounded backoff; do not replay uncertain writes without idempotency. If unplanned or repeated, preserve logs and escalate the platform incident.
