Query performing a large sort or hash join that exceeds `work_mem`. Too many concurrent connections each consuming per-connection memory. Bloated autovacuum workers or background workers consuming excess memory. Server is undersized for the workload

Step 1: Increase `work_mem` carefully — it is per-operation not per-connection: `SET work_mem = '256MB';`. Step 2: Reduce the number of concurrent connections using a connection pooler (PgBouncer).. Step 3: Rewrite memory-intensive queries to use indexes instead of sorts.. Step 4: Add more RAM to the server or use a higher tier on managed PostgreSQL services.

Frequently asked questions

How do I prevent 53200 errors in automated pipelines?

Add retry logic with exponential backoff, validate data quality before loading, and monitor pipeline failures in MetricSign to catch this error early.
