Three pointers:
1. upgrade to v16
2. activate pg_stat_statements and look for the statements that consume most time:
SELECT total_exec_time, calls, query
FROM pg_stat_statements
ORDER BY total_exec_time DESC
LIMIT 10;
3. Look for frequent large sequential scans
SELECT relid::regclass AS table_name,
seq_scan AS sequential_scans,
seq_tup_read / seq_scan AS scan_size
FROM pg_stat_user_tables
WHERE seq_scan > 0
ORDER BY least(seq_scan, seq_tup_read / seq_scan) DESC
LIMIT 10;
Yours,
Laurenz Albe
