| 941 | Minimum tuple length required before trying to move long column values into TOAST tables has been changed | Find base tables in case of which toast_tuple_target storage parameter value is not the default value (2040). "Changing this value may not be useful for very short or very long rows. Note that the default setting is often close to optimal, and it is possible that setting this parameter could have negative effects in some cases. " Make sure that the parameter has an optimal value. | General | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |
| 942 | Partial or case insensitive unique indexes | Find partial or case insensitive unique indexes. These implement uniqueness constraints that are impossible to enforce with the help of SQL's regular UNIQUE constraint. | General | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |

| 944 | Rules with the same name in different schemas | Find rule names that are used in a database in more than one schema. Different things should have different names. But here different rules have the same name. Also make sure that this is not a duplication. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |

| 946 | The number of constraints by schema, by type, and in total | Find the number of constraints in different schemas. The number of constraints in a database gives an indication about the state of enforcing constraints at the database level. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |
| 947 | The number of domains by schema and in total | Identify the number of domains in different schemas. | Sofware measure | INFORMATION_SCHEMA only | 2020-11-06 14:51 | MIT License | |
| 948 | 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 | |
| 949 | The number of user-defined triggers | Triggers can be used to maintain data integrity in a database by causing rejection of data that does not conform to certain rules. Therefore, the number of triggers in a database gives some indications about the state of enforcing constraints at the database level. The query does not count internal triggers. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |
| 950 | The number of user-defined triggers by schema, by type, and in total | Triggers can be used to maintain data integrity in a database by causing rejection of data that does not conform to certain rules. Therefore, the number of triggers in a database gives an indication about the state of enforcing constraints at the database level. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |

| 957 | Triggers with SELECT (i.e., probably check data based on another table) | If a trigger is used for enforcing a constraint, then it should take into account that due to the implementation of multiversion concurrency control (MVCC) in PostgreSQL, reading data does not block data modification and vice versa. Thus, there may be a need to lock the entire table or some row explicitly. | General | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |
| 958 | Triggers with the same name in different schemas | Find trigger names that are used in a database in more than one schema. Different things should have different names.

| 959 | Unlogged tables | Find unlogged tables. These may improve the performance of INSERT operations, but with the price of possibly loosing data - an unlogged table is automatically truncated after a crash or unclean shutdown. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 960 | User-defined composite types | Find composite types that are created by a user, i.e., the type is not created automatically by the database management system based on a relation. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
