| 961 | The number of direct and indirect child tables (table inheritance) | Find the number of direct and all (direct+indirect) child tables of a base table based on the table inheritance. | Sofware measure | system catalog base tables only | 2020-11-14 19:59 | MIT License | |
| 962 | The number of referencing base tables | Find how many base tables reference to a base table by using foreign keys. The more references there are the more impact the change of the table could have to the overall system. | Sofware measure | system catalog base tables only | 2021-03-12 11:02 | MIT License | |

| 964 | The number of schema objects by schema, by type, and in total | Find the number of different types of schema objects in different schemas as well as the total number of schema objects. Show the number of objects that belong to an extension as well as the number of (user-defined) objects that do not belong to an extension. | Sofware measure | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 965 | The number of table constraints with the cardinality bigger than one | Find the number of table constraints with the cardinality bigger than one. Find the number, based on the cardinality, constraint type, and cardinality+constraint type. | Sofware measure | system catalog base tables only | 2020-11-19 13:29 | MIT License | |
| 966 | The number of user-defined rules | Find the number of rules in a database, excluding the rules that are associated with system catalog tables and rules that are created to support views. Rules can be used to maintain data integrity in a database by causing rejection of incorrect insertions and updates. Therefore, the number of rules in a database gives some indications about the state of enforcing constraints at the database level. | Sofware measure | system catalog base tables only | 2022-10-21 11:19 | MIT License | |
| 967 | The number of user-defined rules by schema and in total | Find the number of rules in a database in different schemas, excluding the rules that are created to support views. Rules can be used to maintain data integrity in a database by causing rejection of incorrect insertions and updates. Therefore, the number of rules in a database gives an indication about the state of enforcing constraints at the database level. | Sofware measure | system catalog base tables only | 2022-10-21 11:29 | MIT License | |
| 968 | The same CHECK has a different name in different places | Find the names of table CHECK constraints that have the same Boolean expression but a different naming style in different places (tables). The naming of constraints should be consistent. "If you do something a certain way, do all similar things in the same way." (Robert C. Martin, Clean Code)x | Problem detection | system catalog base tables only | 2024-11-28 14:44 | MIT License | |
| 969 | The same CHECK has a different name in different places (2) | Find the names of table CHECK constraints that have the same Boolean expression but a different naming style in different places (tables).

| 970 | The size of base tables and their indexes | Find the size of base tables without indexes, size of the indexes of the table, total size of the table (including its indexes) and percentage of the index size from the total size. If the size of indexes of a table is relatively high, then check as to whether all the indexes are needed. | General | system catalog base tables only | 2023-10-27 20:38 | MIT License | |

| 978 | Too generic names (candidate key columns) | Find candidate key columns with the names like id, identifikaator, code, kood, number, etc. The names should have a prefix or a suffix. These are too generic names. | Problem detection | system catalog base tables only | 2023-01-20 12:35 | MIT License | |
| 979 | Too generic names (foreign key columns) | Find foreign key columns with the names like id, identifikaator, code, kood, number, etc. The names should have a prefix or a suffix that describes the nature of relationship with the referenced table or at least referes to the referenced table.

| 980 | Too generic names (table constraints) | Find table constraints (constraints that are associated directly with the table) that have too generic names like "key" or the name contain too generic words like "data" (all constraints restrict data in the table), or the name is an abbreviation of a constraint type name. | Problem detection | system catalog base tables only | 2023-01-08 10:40 | MIT License | |
