| 15 |  Beyond indexing, several query optimization techniques can significantly improve performance. | 169 |
| 16 | Unused Indexes: Identify and remove unused indexes to reduce write overhead. The pg_stat_all_indexes view provides information about index usage. | 167 |
| 17 | Index Bloat: As data is inserted, updated, and deleted, indexes can become fragmented and bloated, leading to performance degradation. Rebuild indexes periodically using the REINDEX command. | 161 |
| 18 | Statistics: PostgreSQL relies on statistics to estimate the cost of different query plans. Inaccurate statistics can lead to suboptimal plan choices. Regularly update statistics using the ANALYZE command. | 166 |
| 19 | Partial indexes index only a subset of the table's rows, based on a condition. This can reduce index size and improve performance when queries frequently filter on that condition. | 172 |
| 20 | Composite indexes index multiple columns. The order of columns in a composite index is important. The most frequently used column in WHERE clauses should come first. | 170 |
