What is

PostgresDB 53200: Out of memory

 ?
  1. Check current memory usage:
  2. SELECT pg_size_pretty(pg_database_size(current_database())) AS db_size;
  3. Identify large objects consuming space:
  4. SELECT nspname || '.' || relname AS "relation",
    pg_size_pretty(pg_total_relation_size(C.oid)) AS "total_size"
    FROM pg_class C
    LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace)
    WHERE nspname NOT IN ('pg_catalog', 'information_schema')
    ORDER BY pg_total_relation_size(C.oid) DESC
    LIMIT 10;
  5. Check long-running queries that might be locking resources:
  6. SELECT pid, now() - pg_stat_activity.query_start AS duration, query, state
    FROM pg_stat_activity
    WHERE (now() - pg_stat_activity.query_start) > interval '5 minutes'
    AND state != 'idle'
    ORDER BY duration DESC;
  7. Terminate long-running queries if necessary:
  8. SELECT pg_cancel_backend(pid);
  9. If the issue persists, consider increasing the memory available to PostgreSQL:
    • Temporarily increase the work_mem setting for the current session:
    • SET work_mem = '256MB';
    • For a more permanent solution, modify postgresql.conf and restart the database:
      • Find the file location:
      • SHOW config_file;
      • Edit postgresql.conf, increase work_mem and/or shared_buffers, then restart PostgreSQL.
