| 761 | Unused indexes (2) | Find indexes that are not used by the DBMS. Remember that indexes are not a "free lunch" and they slow down the processes of updating data. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-08-07 16:23 | MIT License | |
| 762 | Unused named input parameters | Find named input parameters that are not referenced in the routine body. All the parameters that are presented in the routine signature declaration must be used in its body. Otherwise these are dead code elements. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-11-05 13:03 | MIT License | |
| 763 | Unused trigger functions | Do not keep in your database elements that are not needed by anybody. These should be put in use or dropped, otherwise these are dead code. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:29 | MIT License | |
| 764 | Updatable views that have not been turned to read only | Find views that are theoretically updatable but do not have INSTEAD OF trigger or DO INSTEAD NOTHING rule to prevent data modifications through the view. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-10-29 10:20 | MIT License | |
| 765 | Update prevention may prevent legal updates | Find triggers that try prevent updating data in a certain column but prevent also certain legal updates - updates that write to a field a value that was in the field before the update. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2022-07-07 13:12 | MIT License | |
| 766 | Updating or deleting data in a routine without restricting rows | Find user-defined routines that contain UPDATE or DELETE statement but do not contain any WHERE clause, meaning that at least one UPDATE or DELETE operation influences all the rows of a table. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-29 13:21 | MIT License | |
| 767 | Usage of base tables | Find for each derived table the list of base tables that are used by the derived table. | General | INFORMATION_SCHEMA+system catalog base tables | 2024-01-14 00:50 | MIT License | |

| 771 | User-defined derived tables | Find user-defined views and materialized views. Pay attention to the outer join operations. One should use these if and only if there is a real need for them. Otherwise they just reduce performance. On the other hand, pay attention that outer join is used where it is logically needed. | General | INFORMATION_SCHEMA+system catalog base tables | 2023-12-11 15:23 | MIT License | |

| 773 | User-defined non-trigger SQL and PL/pgSQL routines | Find the non-trigger SQL and PL/pgSQL routines in non-systemic schemas. | General | INFORMATION_SCHEMA+system catalog base tables | 2024-12-19 10:54 | MIT License | |
| 774 | User-defined routine execution privilege has been granted to PUBLIC | You should follow the principle of least privilege and thus not have in your database user-defined routines that execution privilege is granted to PUBLIC, i.e., to all the database users now and in the future. By default, PostgreSQL gives routine execution privileges to PUBLIC. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:30 | MIT License | |
| 775 | User-defined routines that have the same name as some system-defined routine. | Avoid creating user-defined routines that have the same name as some system-defined routine because it may cause confusion. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:30 | MIT License | |
| 776 | User-defined routines that implement UPSERT operation | Find user-defioned routines that implement UPSERT operation. Make sure that it is consistent with the contracts of database operations. | General | INFORMATION_SCHEMA+system catalog base tables | 2021-10-25 17:02 | MIT License | |

| 778 | User-defined routines that read data | Find user-defined routines that contain SELECT … FROM or PERFORM … FROM operations. PostgreSQL uses multiversion concurrency control (MVCC). Therefore, SELECTs do not block modifications and vice versa. One has to take steps to achieve correct behaviour of data access code. In addition, one should not ask data with multiple queries if it is possible to achieve the result with only one query. | General | INFORMATION_SCHEMA+system catalog base tables | 2023-12-21 15:00 | MIT License | |
