| 104 | Different ways how to find default timestamp values | Find all the default values of base table, view, and foreign table columns that are expressions invoking a function that returns a timestamp. Do it only if there are different expressions, i.e., there could be possible inconsistencies. | Problem detection | INFORMATION_SCHEMA only | 2023-12-08 16:08 | MIT License | |

| 107 | UPDATE triggers | Find all UPDATE triggers. Make sure that they specify a correct set of columns in which data modification will fire the trigger. | General | INFORMATION_SCHEMA only | 2023-12-22 09:47 | MIT License | |

| 109 | All updatable views | Find all views through which it is possible to modify data in base tables. Is_insertable_into and is_updatable show as to whether the view is naturally updatable in PostgreSQL or has associated rules that make sure that INSERT/UPDATE/DELETE operations against the view will not cause an error. Please note that the rule could be DO INSTEAD NOTHING rule, i.e., data modification through the view does not cause an error but the data is not actually modified. If the updatability is achieved due to rules, then is_updatable=YES if the view has both UPDATE and DELETE rule that make sure that UPDATE and DELETE operations do not cause an error. | General | INFORMATION_SCHEMA only | 2024-01-14 17:09 | MIT License | |
