661 | Table, routine, and usage privileges that have been granted to a superuser | Find table, routine, and usage privileges that have been granted to a superuser. Superuser can do anything in the database and thus does not need the privileges. The result is a sign that perhaps the executed GRANT statements were incorrect (wrong username) or the grantee later got superuser status (that it shouldn't have). | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:30 | MIT License | |
662 | Tables without columns | Do not have in a database elements that are not useful. PostgreSQL permits tables with no columns. Such tables can be used to implement Boolean variables (tables TABLE_DEE and TABLE_DUM). On the other hand, such tables might be a result of database evolution, where developers have not noticed that they have dropped all the columns of a table or have not noticed that they have created such a table in the first place. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:29 | MIT License | |
663 | Tables with the same name in different schemas | Find tables with the same name in different schemas. Make sure that this is not a duplication. | General | INFORMATION_SCHEMA+system catalog base tables | 2021-11-10 15:40 | MIT License | |
664 | Temporal function in a simple check constraint is inconsistent with the column type | Find base table columns with a check constraint that refers to a temporal function (current_timestamp, localtimestamp, current_date, or now) that return type is inconsistent with the data type of the column. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-08 21:43 | MIT License | |
665 | Textual columns that have a secondary index but the operator class for the column does not support pattern matching | Find indexed textual columns where the indexing does not consider the possibility of pattern-based search. Such columns do not have an index where the used operator class makes the index suitable for use by queries involving pattern matching expressions. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-07 11:52 | MIT License | |
666 | TG_ARGV is missing | Write correct code. If you pass arguments to a trigger function, then the function should use the arguments. TG_ARGV[]: "Data type array of text; the arguments from the CREATE TRIGGER statement. The index counts from 0. Invalid indexes (less than 0 or greater than or equal to tg_nargs) result in a null value."

667 | The expression of a simple check constraint that is associated directly with a column needs type conversion | Find check constraints that involve one column and are associated directly with a table where the Boolean expression invokes an operation that does not match with the data type of the column. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:29 | MIT License | |
668 | The generator of surrogate key values can output the same value more than once | Find surrogate keys where the generator can output the same value more than once. Key values must be unique, i.e., at some point the generator will prevent adding new rows to the table. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-03-08 00:40 | MIT License | |
669 | The generic names (columns) (aggregate view) | Find the too generic column names and the number of their occurrences. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-01-15 10:34 | MIT License | |
670 | The generic names (columns) (aggregate view)(2) | Find the number of too generic base table and view column names. Do not differentiate between base table and view columns to determine what name is generic. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-01-18 16:42 | MIT License | |
671 | The longest names of database objects | Find the TOP 3 longest (identifiers) names of user-defined objects. | General | INFORMATION_SCHEMA+system catalog base tables | 2023-03-18 17:22 | MIT License | |
672 | The longest names of database objects by object type | "Names in software are 90 percent of what make software readable. You need to take the time to choose them wisely and keep them relevant. Names are too important to treat carelessly. Names should not cause confusion." (Robert C. Martin, Clean Code) Names should be expressive. Find the TOP 3 longest (identifiers) names of user-defined objects by their type. These could be the first candidates of renaming in order to give to database objects better names. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-03-17 01:09 | MIT License | |
673 | The name of the routine does not match with the action of the routine | Find user-defined non-trigger SQL and PL/pgSQL routines where the beginning of the name of the routine indicates a certain action inside the routine (INSERT, UPDATE, or DELETE) but there is no such statement in the routine body. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2022-11-19 14:37 | MIT License | |
674 | The number and percentage of different names of database objects | Names should be expressive. Find the number of different names used in a database as well as the number of named database objects, and the percentage of different names from all the names. Names should be expressive. Different objects should have different names. The smaller the percentage the less descriptive are the names in the database. Find the number of different names (identifiers) of user-defined database objects and compare it with the total number of database objects. The values could be used to compare different databases. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-03-18 17:12 | MIT License | |
675 | The number and percentage of different names of database objects by object type | "Names in software are 90 percent of what make software readable. You need to take the time to choose them wisely and keep them relevant. Names are too important to treat carelessly. Names should not cause confusion." (Robert C. Martin, Clean Code) Names should be expressive. Different objects should have different names. The smaller the percentage the less descriptive are the names in the database. Find the number of different names (identifiers) of user-defined database objects by the object type and compare it with the total number of database objects with this type. The values could be used to compare different databases. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-03-16 15:38 | MIT License | |
676 | The number of columns based on table type | Find the total number of columns in the different types of tables as well as average number of columns in the tables as well as minimal and maximal number of columns. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2022-11-10 14:12 | MIT License | |
677 | The number of commented routines | Find the number of commented routines based on the way how the comments have been added (as a COMMENT object or as a comment in the routine body). | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2024-01-14 20:49 | MIT License | |
678 | The number of constraints by schema, by type, and in total | Find the number of constraints in different schemas. The number of constraints in a database gives an indication about the state of enforcing constraints at the database level. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |
679 | The number of derived table columns with an array, a user-defined, XML, JSON, or JSONB type | Find the number of derived table columns with json, xml, array, or user-defined types. Such columns may contain data that has been aggregated/composed based on values in base tables. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-01-14 20:22 | MIT License | |
680 | The number of names of database objects by the number of subcomponents in the names | "Names in software are 90 percent of what make software readable. You need to take the time to choose them wisely and keep them relevant. Names are too important to treat carelessly. Names should not cause confusion." (Robert C. Martin, Clean Code) Names should be expressive. Find the number of names (identifiers) of user-defined database objects by the number of subcomponents in the names. The values could be used to compare different databases. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-03-18 17:02 | MIT License |
