| 281 | Full text search columns with other type of index than gin or gist index | Find columns of base tabels and materialized views with the type tsvector that do not have a gin or a gist index but have another type of index (e.g., b-tree). Gin and Gist are the preferred index types for text search. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-07 09:22 | MIT License | |
| 282 | Full text search columns that have no gin or gist index | Find columns of base tabels and materialized views with the type tsvector that do not have a gin or a gist index. These are the preferred index types for text search. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-07 09:22 | MIT License | |
| 283 | Preventing strings that consist of only spaces instead of strings that consist of only whitespace characters | Find columns of base tables and foreign tables where one uses a check constraint to prevent values that consist of only spaces. Make sure that this is the correct constraint and there is no need to prevent values that consist of only whitespace characters. | Problem detection | INFORMATION_SCHEMA only | 2021-02-25 17:29 | MIT License | |
| 284 | Incorrect prevention of the empty string or strings that consist of only spaces in a field | Find columns of base tables and foreign tables where the requirement that there should not be empty strings or strings that consist of only spaces in the column has been implemented incorrectly - by using the constraint trim(column_name) IS NOT NULL. PostgreSQL (differently from Oracle) does not replace the empty string with NULL. Empty string is a value but NULL is a special marker that denotes a missing value. Thus, in case of such constraint the DBMS checks a proposition '' IS NOT NULL. This is a true proposition and the DBMS does not prevent registration of such a row. | Problem detection | INFORMATION_SCHEMA only | 2021-02-25 17:29 | MIT License | |

| 286 | Only one value permitted in a non-inherited base table or a foreign table column (based on check constraints) | Find columns of base tables or foreign tables in case of which a check constraint on the column permits only one value in the column. Exclude columns that are inherited from a supertable because the constraint may be correct if it is applied to a column of a subtable that is inherited from the supertable. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-04-30 20:16 | MIT License | |
| 287 | Only one value permitted in a base table or a foreign table column (based on check constraints) | Find columns of base tables or foreign tables in case of which a check constraint on the column permits only one value in the column. The constraint may be correct if it is applied to a column of a subtable that is inherited from the supertable or is used to enfore the rule that the table can have at most one row. | General | INFORMATION_SCHEMA+system catalog base tables | 2024-04-30 20:14 | MIT License | |
| 288 | Only one value permitted in a base table or a foreign table column (based on enumeration types) | Find columns of base tables or foreign tables in case of which the type of the column permits only one value in the column. The type is an enumeration type that specifies only one value. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:30 | MIT License | |
| 289 | Inappropriate field size or data type for column that strores database username | Find columns of base tables that based on the default value of the column contain database username. However, the type of the column is not VARCHAR(63) or VARCHAR(128). | Problem detection | INFORMATION_SCHEMA only | 2023-11-19 11:58 | MIT License | |
| 290 | Potentially missing PRIMARY KEY or UNIQUE constraints (based on sequence generators) | Find columns of base tables that contain automatically generated unique values but do not belong to any PRIMARY KEY/UNIQUE constraint. If something has to be unique, then it must be said to the system so that it could use the information for internal optimizations and enforce the constraint. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-03-07 20:53 | MIT License | |
| 291 | Columns of base tables that hold truth values that do not have a default value although they could have it (non-Boolean columns) | Find columns of base tables that do not have type BOOLEAN but are used to record Boolean values. Based on column names these implement a state machine or record agreements. At the same time the columns do not have a default value. There are only two truth values - TRUE and FALSE - in case of two-valued logic. It should be possible to select one of these as the default value of the column. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-09 16:40 | MIT License | |

| 293 | Incorrect data type (based on default values) | Find columns of base tables that have the default value CURRENT_USER or SESSION_USER but the data type is CHAR or TEXT. | Problem detection | INFORMATION_SCHEMA only | 2023-12-30 11:06 | MIT License | |
| 294 | Incorrect field size (based on default values) | Find columns of base tables that have the default value CURRENT_USER or SESSION_USER but the field size is not 63 (default maximum identifier length in PostgreSQL). | Problem detection | INFORMATION_SCHEMA only | 2023-12-30 11:05 | MIT License | |
| 295 | Perhaps incorrect column name (based on default values) | Find columns of base tables that have the default value CURRENT_USER or SESSION_USER but the name of the column does not refer to the fact that it contains usernames. | Problem detection | INFORMATION_SCHEMA only | 2024-01-01 12:14 | MIT License | |
| 296 | Columns of base tables that hold truth values that do not have a default value although they could have it (Boolean columns) | Find columns of base tables that have type BOOLEAN.

| 297 | Columns of base tables that hold truth values but do not have a default value (Boolean columns) | Find columns of base tables that have type BOOLEAN but do not have a default value. There are only two truth values - TRUE and FALSE - in case of two-valued logic. Often it should be possible to select one of these as the default value of a column that has BOOLEAN type. | Problem detection | INFORMATION_SCHEMA only | 2023-11-09 13:14 | MIT License | |
| 298 | Registration/modification time is not automatically set | Find columns of base tables that name and type suggest that the column should contain the row registration time or last modify time but the column does not have a default value. | Problem detection | INFORMATION_SCHEMA only | 2021-03-28 17:36 | MIT License | |
| 299 | Potentially missing PRIMARY KEY or UNIQUE constraints (based on column names) | Find columns of base tables that name refers to the possibility that it contains unique values but the column does not belong to any PRIMARY KEY/UNIQUE constraint.

| 300 | Perhaps the type of a base table column should be an integer type (based on column names) | Find columns of base tables where the name of the column has prefix or suffix "id" or has the name "id" but the column does not have an integer type or uuid type. A convention is to use the phrase "id" in the names of surrogate key columns. | Problem detection | INFORMATION_SCHEMA only | 2023-11-08 13:31 | MIT License | |
