| 363 | FILLFACTOR is probably too big | Find base tables in case of which the FILLFACTOR property has perhaps a too big value. Try to find base tables that probably encounter UPDATE operations. In the tables that have frequent updates you want to have free space in table pages (blocks) to accommodate new row versions, which the system automatically creates as a result of fulfilling UPDATE statements. If a new row version will be put to another page by the system, then it means that table indexes have to be updated as well. Thus, the more there are indexes, the more the table would benefit from keeping a new row version in the same page as the old version. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-12-17 00:22 | MIT License | |
| 364 | FILLFACTOR is probably too small | Too small fillfactor wastes storage space. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2022-11-02 10:43 | MIT License | |
| 365 | Find all non-foreign key columns of base tables | Find all non-foreign key columns of base tables. Make sure that no foreign key constraint is missing. | General | INFORMATION_SCHEMA+system catalog base tables | 2020-11-21 02:59 | MIT License | |
| 366 | Find all publications | Find publications of tables that have been created in order to enable logical replication. | General | INFORMATION_SCHEMA+system catalog base tables | 2020-11-18 15:09 | MIT License | |
| 367 | Flag parameters | A Boolean parameter may be used to determine what task to fulfill. In this case the routine has multiple tasks and does not satisfy the separation of concerns principle. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-11-04 10:48 | MIT License | |
| 368 | Foreign key column has a default value that is not present in the parent table | Find foreign key columns that have a default value that is not present in the parent table. Identify default values that cause violations of the referential constraints. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:30 | MIT License | |
| 369 | Foreign key columns that are associated with a sequence generator | Find foreign key columns that are associated with a sequence generator. Foreign key values are selected amongst the values that are registered as corresponding primary key/unique key values. Values in the foreign key columns are not directly generated by the system. These values might be system generated indirectly - generated when a row is added to the primary (parent) table. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-03-08 00:42 | MIT License | |
| 370 | Foreign key columns that do not have an integer or varchar type | Find foreign key columns that do not have smallint, integer, bigint, or varchar(n) type. These are the most commonly used types in case of key/foreign key columns. Although the use of other types would be perfectly legal as well, make sure that you have selected the best possible data type for each and every column. | General | INFORMATION_SCHEMA+system catalog base tables | 2020-11-16 10:14 | MIT License | |
| 371 | Foreign key columns that have no index | Find foreign key columns that do not have an index. Foreign key columns are often used for performing join operations. It is useful to index such columns. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:30 | MIT License | |

| 373 | Foreign servers without user mappings | Find foreign servers that do not have any associated user mappings. "A user mapping typically encapsulates connection information that a foreign-data wrapper uses together with the information encapsulated by a foreign server to access an external data resource." | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:29 | MIT License | |
| 374 | FOR UPDATE in derived tables | Find derived tables that subquery uses FOR UPDATE construct. Reading a data element shouldn't block other read operations of the same element. Thus, you shouldn't use exclusive locking command in a view. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2022-12-12 11:11 | MIT License | |
| 375 | FOR UPDATE is not allowed with aggregate functions | Implement explicit locking correctly. Instead of writing, for instance, SELECT Count(*) AS cnt FROM person WHERE person_id=1 FOR UPDATE; one has to write SELECT person_id FROM person WHERE person_id=1 FOR UPDATE; | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-11-04 11:23 | MIT License | |
| 376 | FOR UPDATE is not needed if there is no FROM clause in the SELECT statement | Find routines that use SELECT … FOR UPDATE without selecting rows from a specific table. For instance: SELECT 'text' AS v FOR UPDATE; | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-11-05 14:10 | MIT License | |

| 378 | Frequency of lengths of the names of database objects | "Names in software are 90 percent of what make software readable. You need to take the time to choose them wisely and keep them relevant. Names are too important to treat carelessly. Names should not cause confusion." (Robert C. Martin, Clean Code) Names should be expressive. Find how many names (identifiers) of database objects there are with different lengths. The values could be used to compare different databases. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-03-17 01:10 | MIT License | |

Names are too important to treat carelessly. Names should not cause confusion." (Robert C. Martin, Clean Code) Names should be expressive. Find, what are the most popular components of the names (identifiers) of user-defined database objects, assuming, that the separator of the components is "_". | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-03-17 10:12 | MIT License | |
