Such use of the modifiers is not supported by PostgreSQL. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-11-04 16:06 | MIT License | |

| 453 | Lifecycle not initiated | Find non-primary key and non-unique base table foreign key columns that name refers to the possibility that these are used to register references to a state classifier. The column must belong to a foreign key and does not have a default value. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-26 15:40 | MIT License | |

| 457 | Logical size of a schema | The schema size is the sum of the sizes of all tables in the schema. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2022-10-21 16:18 | MIT License | |
| 458 | Logical size of a table | The table size is the sum of the total size of the simple columns and the total size of the complex columns in the table. In case of SQL databases large base tables in terms of number of columns could be a side effect of the problems with cloned columns or multiple columns for the same attribute. A base table with a low normalization level, which is meant to hold data that corresponds to multiple entity types has typically also relatively large number of columns compared with other base tables. Thus, the normalization level of base tables with a large number of columns should be checked as well. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2022-10-21 16:17 | MIT License | |
