PostgreSQL Query Catalog

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 Publications with no tables Find publications that do not contain any table. Problem detection system catalog base tables only 2021-02-25 17:30 MIT License View
942 PUBLIC has TEMPORARY privilege in the database Find as to whether PUBLIC (all current and future users) has TEMPORARY privilege in the database. PUBLIC gets the privilege by default. Problem detection system catalog base tables only 2021-12-31 15:52 MIT License View
943 Recursive relationships with the same source and target Find incorrectly implemented adjacency lists. Problem detection system catalog base tables only 2021-02-25 17:30 MIT License View
944 Recursive rules that directly modify their home table Do not cause potentially infinite loops. Recursive rules would fire itself over and over again. Although the system is able to detect these after executing a data modification statement it is better to avoid creating these altogether.

945 Redundant indexes Find indexes that may be redundant. In addition to identical indexes it also considers indexes that cover the same columns and have the same properties except uniqueness. The query considers all types of indexes, including indexes that have been automatically created to support a constraint and function-based indexes.

946 Referential degree of tables (ver 2) Find how many base tables are referenced from a base table by using foreign keys. Sofware measure system catalog base tables only 2021-03-12 11:06 MIT License View
947 Rules with the same name in different schemas Find rule names that are used in a database in more than one schema. Different things should have different names. But here different rules have the same name. Also make sure that this is not a duplication. General system catalog base tables only 2020-11-06 14:51 MIT License View
948 Rules with the same name within the same schema Find names of rules that are used within the same schema more than once. Give different triggers different names. Problem detection system catalog base tables only 2021-02-25 17:30 MIT License View
949 Sequences that are not owned by a table column Find sequence generators that are not owned by a table column, i.e., if one drops the table or the column, then the sequence generator stays in place. Problem detection system catalog base tables only 2023-10-06 14:40 MIT License View
950 Short cycle (columns) Find cases where two candidate keys of the same table that are also foreign keys reference to each other. Problem detection system catalog base tables only 2021-11-28 02:08 MIT License View
951 Simple primary keys that column name does not contain the table name Find simple primary keys that column name does not contain the table name. The naming should be clear and consistent. Problem detection system catalog base tables only 2023-03-19 10:35 MIT License View
952 System-generated table constraint names (constraints that involve one column) Find the names of database constraints that have been system-generated. Additional restrictions are that the constraints must involve only one column and are associated directly with a table (not through a domain). Names should follow the same style. If there is a mix of system-generated and user-defined names, then the style is most probably different. Problem detection system catalog base tables only 2021-12-10 12:47 MIT License View
953 Table constraints with the cardinality bigger than one Find constraints that involve more than one columns. Check as to whether the names follow a common style or not. General system catalog base tables only 2020-11-19 13:34 MIT License View
954 Table constraints with the same name (constraints connected directly with a base table or a foreign table) Find base table and foreign table constraint names that are used in a database more than once (possibly in different schemas or in case of different types of constraints). Different things should have different names. But here different constraints have the same name. Also make sure that this is not a sign of duplication.

955 Table inheritance Find inheritance between base tables. Use table inheritance carefully because, for instance, certain constraints are not inherited and must be redefined on child tables. General system catalog base tables only 2020-11-15 13:02 MIT License View
956 Table inheritance (path view) Find in case of each base table that participates in a table inheritance hierarchy the path to the table from the top-level table. Use table inheritance carefully because, for instance, certain constraints are not inherited and must be redefined on child tables. Also make sure that the identifier of each child table in an inheritance hierarchy is a hyponym of the identifier of its parent table.

957 Tables that have associated user triggers Find information about tables that are associated with triggers. General system catalog base tables only 2020-11-06 14:51 MIT License View
958 The longest referential paths Find the longest referential paths between the tables regardless of the schema that contain the tables. Sofware measure system catalog base tables only 2020-11-14 15:42 MIT License View
959 The name of the base table that implements a binary relationship type does not explain the meaning of the relationship Find base tables that implement a binary relationship type (have two foreign keys) and the name of the table consist of the names of tables that this (intermediate) table connect. The names should be derived from the domain. For instance, instead of name Course_Lecturer it is better to have name Teaching.

960 The number of compensating actions of foreign key constraints Find the number of compensating actions that are specified in case of foreign key constraints. Sofware measure system catalog base tables only 2020-11-16 10:11 MIT License View
