PostgreSQL Query Catalog

Project on GitHub
Filter Queries

Found 997 queries.

  • All the queries about database objects contain a subcondition to exclude from the result information about the system catalog.
  • Although the statements use SQL constructs (common table expressions; NOT in subqueries) that could cause performance problems in case of large datasets it shouldn't be a problem in case of relatively small amount of data, which is in the system catalog of a database.
  • Statistics about the catalog content and project home in GitHub that has additional information.

941 Unused trigger functions Do not keep in your database elements that are not needed by anybody. These should be put in use or dropped, otherwise these are dead code. Problem detection INFORMATION_SCHEMA+system catalog base tables 2021-02-25 17:29 MIT License View
942 Updatable views that do not have WITH CHECK OPTION constraint Find updatable views that do not have WITH CHECK OPTION constraint. WITH CHECK OPTION constraint prevents updates through the view that violate the predicate of the view. Such updates must be prevented.

943 Updatable views that have not been turned to read only Find views that are theoretically updatable but do not have INSTEAD OF trigger or DO INSTEAD NOTHING rule to prevent data modifications through the view.

944 Updatable views with WHERE clause that do not have WITH CHECK OPTION constraint Find updatable views that restrict rows, i.e., have WHERE clause, but do not have WITH CHECK OPTION constraint. WITH CHECK OPTION constraint prevents updates through the view that violate the predicate of the view. Such updates must be prevented.

945 Updataple foreign tables that refer to another PostgreSQL table Find foreign tables that have been defined based on postgresql_fwd foreign data wrapper and that are updatable. Make sure that updatability is in this case needed. General INFORMATION_SCHEMA only 2020-11-06 17:15 MIT License View
946 Update prevention may prevent legal updates Find triggers that try prevent updating data in a certain column but prevent also certain legal updates - updates that write to a field a value that was in the field before the update.

947 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 View
948 UPDATE triggers where updated columns have not been specified (the trigger could executed too often) Find UPDATE triggers where updated columns are not specified. These triggers could be executed too often because unneeded executions are not prevented. Problem detection INFORMATION_SCHEMA only 2024-12-23 09:53 MIT License View
949 UPDATE triggers where WHEN clause has not been specified (the trigger could executed too often) Find UPDATE triggers where WHEN clause is not specified. These triggers could be executed too often because unneeded executions are not prevented. Problem detection INFORMATION_SCHEMA only 2024-12-23 09:54 MIT License View
950 Updating or deleting data in a routine without restricting rows Find user-defined routines that contain UPDATE or DELETE statement but do not contain any WHERE clause, meaning that at least one UPDATE or DELETE operation influences all the rows of a table.

951 Usage of base tables Find for each derived table the list of base tables that are used by the derived table. General INFORMATION_SCHEMA+system catalog base tables 2024-01-14 00:50 MIT License View
952 Used indexes Find indexes that are used by the DBMS. General INFORMATION_SCHEMA+system catalog base tables 2024-08-07 16:23 MIT License View
953 Use invocation of a precise function instead of casting in a default value expression Be precise and write as little code as possible. Prefer expressions with simple invocations of functions like localtimestamp, current_timestamp, and current_date over expressions like (now())::date. Find table columns that have a default value that casts the type of the returned value of a non-deterministic function (now, localtimestamp, current_timestamp, and current_date).

954 Useless type indication Find columns and parameters where the type of the identifier is perhaps explicitly indicated in the name. Problem detection INFORMATION_SCHEMA+system catalog base tables 2023-11-10 14:47 MIT License View
955 Useless type indication (2) Find columns and parameters where the type of the identifier is perhaps explicitly indicated in the name. Problem detection INFORMATION_SCHEMA+system catalog base tables 2023-11-10 14:55 MIT License View
956 User-defined composite types Find composite types that are created by a user, i.e., the type is not created automatically by the database management system based on a relation. General system catalog base tables only 2020-11-06 14:51 MIT License View
957 User-defined derived tables Find user-defined views and materialized views. Pay attention to the outer join operations. One should use these if and only if there is a real need for them. Otherwise they just reduce performance. On the other hand, pay attention that outer join is used where it is logically needed.

958 User-defined non-trigger routines without parameters Find user-defined non-trigger routines with no parameters. General INFORMATION_SCHEMA+system catalog base tables 2021-11-03 20:05 MIT License View
959 User-defined non-trigger SQL and PL/pgSQL routines Find the non-trigger SQL and PL/pgSQL routines in non-systemic schemas. General INFORMATION_SCHEMA+system catalog base tables 2024-12-19 10:54 MIT License View
960 User-defined routine execution privilege has been granted to PUBLIC You should follow the principle of least privilege and thus not have in your database user-defined routines that execution privilege is granted to PUBLIC, i.e., to all the database users now and in the future. By default, PostgreSQL gives routine execution privileges to PUBLIC. Problem detection INFORMATION_SCHEMA+system catalog base tables 2021-02-25 17:30 MIT License View
