| 790 | Base table columns where TOAST-ing strategy has been changed | 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 so that it is different than the default strategy determined by the type. Make sure that the new strategy is optimal. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 791 | 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. It means that potentially, if a value in the column is large enough, it is not possible to save the row. | Problem detection | system catalog base tables only | 2021-02-25 17:29 | MIT License | |
| 792 | Base table columns with a composite type | Find base table columns with a composite type. Think through as to whether a column with a composite type could be replaced with a separate table. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 793 | Base table columns with CITEXT type | Find base table columns with CITEXT type and make sure that case insensitivity is really needed in case of this column. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 794 | Base tables created based on a type | Find base tables that have been created based on a composite type and thnk through as to whether it was really needed. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 795 | Base tables that do not have a TOAST table | Find base tables that (due to the types of their columns) do not have an associated TOAST table for storing out-of-line data. | General | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
| 796 | Base tables that have more than five indexes | Find base tables that have more than five indexes. Indexes can be used to increase the speed of queries (SELECT statements). However, the amount of indexes shouldn't be too large. Otherwise it may reduce the speed of operations that are used to modify data. | Problem detection | system catalog base tables only | 2022-10-21 10:33 | MIT License | |
| 797 | Base tables with exactly one key | Find all base tables that have exactly one PRIMARY KEY or UNIQUE constraint. Find and enforce all the keys. Are you sure there are not more keys in the table? | General | system catalog base tables only | 2021-10-16 10:39 | MIT License | |
