    n_dead_tup,
    last_vacuum,
    last_autovacuum
FROM pg_stat_user_tables
WHERE n_dead_tup > 1000
ORDER BY n_dead_tup DESC;

-- Connection monitoring
SELECT 
    state,
    COUNT(*) as connection_count,
    AVG(EXTRACT(EPOCH FROM (now() - state_change))) as avg_duration
FROM pg_stat_activity
WHERE state IS NOT NULL
GROUP BY state;

) PARTITION BY RANGE (sale_date);

CREATE TABLE sales_2024_q1 PARTITION OF sales_data
    FOR VALUES FROM ('2024-01-01') TO ('2024-04-01');

CREATE TABLE sales_2024_q2 PARTITION OF sales_data
    FOR VALUES FROM ('2024-04-01') TO ('2024-07-01');

-- Connection pooling optimization
-- PgBouncer configuration for high-traffic applications
[databases]
