941 | The number of tables by schema, by type, and in total | Find the number of tables (base, foreign, and derived) in different schemas. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2021-03-07 10:57 | MIT License | |
942 | The number of user-defined non-trigger routines by schema, by language, and by routine type | Find the number of user-defined non-trigger routines based on their schema, language, and routine type. The routines can be used to implement virtual data layer. Thus the queriy gives some indications about the possible extent of the layer. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2024-01-14 20:53 | MIT License | |
943 | The number of user-defined non-trigger routines by schema, by security type, and by being deterministic | Find the number of user-defined non-trigger routines based on their schema, security type, and being deterministic. The routines can be used to implement virtual data layer. Thus the queriy gives some indications about the possible extent of the layer. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2024-01-14 20:52 | MIT License | |
944 | The number of user-defined routines based on their database usage | Find the number of non-extension routines in a database that modify data. The routines can be used to implement virtual data layer. Thus the queriy gives some indications about the possible extent of the layer. The query distinguishes trigger and non-trigger routines, thus it also gives information about triggers that modify data. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2024-01-15 00:38 | MIT License | |
945 | The number of user-defined rules | Find the number of rules in a database, excluding the rules that are associated with system catalog tables and rules that are created to support views. Rules can be used to maintain data integrity in a database by causing rejection of incorrect insertions and updates. Therefore, the number of rules in a database gives some indications about the state of enforcing constraints at the database level. | Sofware measure | system catalog base tables only | 2022-10-21 11:19 | MIT License | |
946 | The number of user-defined rules by schema and in total | Find the number of rules in a database in different schemas, excluding the rules that are created to support views. Rules can be used to maintain data integrity in a database by causing rejection of incorrect insertions and updates. Therefore, the number of rules in a database gives an indication about the state of enforcing constraints at the database level. | Sofware measure | system catalog base tables only | 2022-10-21 11:29 | MIT License | |
947 | The number of user-defined triggers | Triggers can be used to maintain data integrity in a database by causing rejection of data that does not conform to certain rules. Therefore, the number of triggers in a database gives some indications about the state of enforcing constraints at the database level. The query does not count internal triggers. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2020-11-06 14:51 | MIT License | |
948 | The number of user defined triggers by different characteristics | Find the number of user defined triggers by action orientation (ROW, STATEMENT), action timing (BEFORE, AFTER, INSTEAD OF), and event type (INSERT, UPDATE, DELETE) and their combinations. | Sofware measure | INFORMATION_SCHEMA only | 2024-01-14 17:41 | MIT License | |
949 | The number of user-defined triggers by schema, by type, and in total | Triggers can be used to maintain data integrity in a database by causing rejection of data that does not conform to certain rules. Therefore, the number of triggers 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 | |
950 | The proportion of mandatory and optional textual base table columns | Find the number of textual base table columns, the number of optional textual base table columns (permit NULLs), and the number of mandatory textual base table columns (do not permit NULLs). | Sofware measure | INFORMATION_SCHEMA only | 2021-01-15 17:39 | MIT License | |
951 | The proportion of using different integer types as types of base table columns | Find the number of base table columns that use different integer types (SMALLINT, INTEGER, BIGINT) and their proportion from the overall set of columns that use an integer type. | Sofware measure | INFORMATION_SCHEMA only | 2021-03-03 12:41 | MIT License | |
952 | The storage size of each index (the system catalog excluded) | Get overview of disk usage. | Sofware measure | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
953 | The storage size of each schema data object (the system catalog excluded) | Get overview of disk usage by different schema objects that contain user data. | Sofware measure | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
954 | The storage size of each table (including indexes) (the system catalog excluded) | Get overview of disk usage. | Sofware measure | system catalog base tables only | 2020-11-06 14:51 | MIT License | |
955 | The total number of physical lines of code in the bodies of user-defined SQL and PL/pgSQL functions/procedures | Find a numerical measure that describes the extent of the database public interface (virtual data layer) through which users access the database. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2021-11-04 21:02 | MIT License | |
956 | The total size of all indexes (system catalog excluded) | Sofware measure | system catalog base tables only | 2023-05-14 11:04 | MIT License | ||
957 | The total size of all tables (system catalog excluded) | Sofware measure | system catalog base tables only | 2023-05-14 11:04 | MIT License | ||
958 | The total storage size of all indexes (the system catalog excluded) | Get overview of disk usage. | Sofware measure | system catalog base tables only | 2020-11-06 14:51 | MIT License | |

960 | The usage of double vs singular underscores or spaces in names as separator of name components | Improve the readability of names. Find the number of names (identifiers) of user-defined database objects that contain two or more consecutive underscores or spaces as the separator of name components vs. the number of names that contain a single underscore or space to separate name components. Try to be consistent in the usage of underscores. | Sofware measure | INFORMATION_SCHEMA+system catalog base tables | 2023-03-17 11:11 | MIT License |
