| 67 | Base table columns permitting e-mail addresses without @ sign | Find non-foreign key base table columns that name refers to the possibility that these are used to register e-mail addresses. Find the columns that do not have any simple CHECK constraint that contains @ sign. A simple check constraint covers a single column. In this case registration of e-mail addresses without @ is most probably not prohibited. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:29 | MIT License | |
| 68 | Base table columns permitting empty strings and strings that consist of only whitespace characters | Find non-foreign key columns of base tables that have a textual type and do not have any simple CHECK constraint, i.e., a constraint that involves only one column. Such columns can contain the empty string and strings that consist of only whitespace. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:29 | MIT License | |
| 69 | Base table columns permitting empty strings and strings that consist of only whitespace characters (2) | Find non-foreign key columns of base tables that have a textual type and do not have a simple CHECK constraint (i.e., a constraint that involves only one column) that seems to prohibit empty strings and strings that consist of only whitespace as well as a simple CHECK constraint that specifies permitted symbols. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-01-02 16:52 | MIT License | |
| 70 | Base table columns permitting negative prices/quantity | Find non-foreign key base table columns that name refers to the possibility that these are used to register prices/quantities. Find the columns that do not have any simple CHECK constraints, i.e., a constraint that covers only this column. In this case registration of negative price/quantity is most probably not prohibited. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-10-06 14:14 | MIT License | |
| 71 | Base table columns permitting telephone numbers without digits | Find non-foreign key base table columns that name refers to the possibility that these are used to register phone numbers. Find the columns that do not have any simple CHECK constraint that references to the character class of digits. A simple check constraint covers a single column. In this case registration of e-mail addresses without digits is most probably not prohibited. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-09 12:52 | MIT License | |
| 72 | Base table columns permitting temporal values that may be outside the range of logical values | Find base tables columns with temporal types (date and timestamp) that do not belong to a foreign key and that do not have any associated simple CHECK constraints, i.e., constraint that involves only one column. For instance, in the column registration_time that does not have any associated CHECK constraints could be values '1200-01-01 00:00' or '5900-12-31 00:00'. Rows with these values most probably represent wrong propositions and the system should restrict registration of such data. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-12-17 00:40 | MIT License | |

Make sure that the new strategy is optimal. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 76 | Base table columns where TOAST-ing strategy has been changed to plain | Find base table columns in case of which the system can use TOAST technique (due to the data type of the column) and where the toasting strategy has been changed to plain.
