-## Maintain Table Statistics with VACUUM and ANALYZE
-
-Outdated statistics cause the query planner to make poor decisions. VACUUM reclaims space, ANALYZE updates statistics.
-
-**Incorrect (stale statistics):**
-
-```sql
--- Table has 1M rows but stats say 1000
--- Query planner chooses wrong strategy
-explain select * from orders where status = 'pending';
--- Shows: Seq Scan (because stats show small table)
--- Actually: Index Scan would be much faster
-```
-
-**Correct (maintain fresh statistics):**
-
-```sql
--- Manually analyze after large data changes
-analyze orders;
-
--- Analyze specific columns used in WHERE clauses
-analyze orders (status, created_at);
-
--- Check when tables were last analyzed
-select
-  relname,
-  last_vacuum,
-  last_autovacuum,
-  last_analyze,
-  last_autoanalyze
-from pg_stat_user_tables
-order by last_analyze nulls first;
-```
-
-Autovacuum tuning for busy tables:
-
-```sql
--- Increase frequency for high-churn tables
-alter table orders set (
-  autovacuum_vacuum_scale_factor = 0.05,     -- Vacuum at 5% dead tuples (default 20%)
-  autovacuum_analyze_scale_factor = 0.02     -- Analyze at 2% changes (default 10%)
-);
-
--- Check autovacuum status
-select * from pg_stat_progress_vacuum;
-```
