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.

161 Patterns of the names of columns of simple primary keys Find the patterns of the names of columns of simple primary keys. Make sure that the naming is consistent. Ideally, the names should indicate as to whether the column is a surrogate or a natural key column. PostgreSQL 14 added primary keys, unique constraints, and foreign keys to system catalogs. Thus the query was modified to exclude the results from the system catalog. General system catalog base tables only 2023-01-20 13:40 MIT License View
162 Patterns of the names of PRIMARY KEY, UNIQUE, CHECK, EXCLUDE, and FOREIGN KEY constraints as well as user-defined non-unique indexes that are associated with exactly one column Find patterns of the names of constraints and indexes. Make sure that the naming is consistent. General INFORMATION_SCHEMA+system catalog base tables 2023-01-14 20:52 MIT License View
163 Patterns of the names of PRIMARY KEY, UNIQUE, CHECK, EXCLUDE, and FOREIGN KEY constraints as well as user-defined non-unique indexes that are associated with two or three columns Find patterns of the names of constraints and indexes. Make sure that the naming is consistent. General INFORMATION_SCHEMA+system catalog base tables 2023-01-14 20:52 MIT License View
164 Patterns of the names of triggers and rules Find the patterns of the names of trigger and rule names. Make sure that the naming is consistent. General INFORMATION_SCHEMA+system catalog base tables 2023-01-14 20:51 MIT License View
165 Perhaps IS DISTINCT FROM should be used instead of <> in WHEN clauses Use a right predicate in trigger condition in order to ensure that the trigger executes always when it has to but not more often. IS DISTINCT FROM treats NULL as if it was a known value, rather than unknown. It would be relevant if a column that is referenced in the action condition is optional, i.e., permits NULLs.

166 PL/pgSQL routines that use a cursor Working with sets of rows rather than processing each row separately is more effective. General INFORMATION_SCHEMA+system catalog base tables 2021-11-04 11:54 MIT License View
167 Polymorphic routines Find routines that have a parameter (input or output) that can have values from different types. This parameter has one of the PostgreSQL polymorphic types. The set of polymorphic types in PostgreSQL is a proper subset of its pseudo-types. The use of such a parameter allows a single routine definition to operate on many different data types, with the specific data type(s) being determined by the data types actually passed to it in a particular call.

168 Potentially a classifier is missing (based on field sizes) Find columns that are not covered by a primary key, unique, and foreign key constraint but have a textual type with the maximum field size 3 or less.

169 Prefixes in the names of database objects Find for different types of database objects all the prefixes that are used in different names. One should be consistent in naming, including in the use of prefixes. If you use prefix in the name of a database object, then it could refer to the type of the database object. Do not use different prefixes in the names of database objects that have the same type. General INFORMATION_SCHEMA+system catalog base tables 2024-12-21 16:22 MIT License View
170 Privileges on the database and its schemas, domains, types, languages, sequences, foreign data wrappers, and foreign servers Find privileges on the database and its schemas, domains, types, languages, sequences, foreign data wrappers, and foreign servers that are not for the owner and not for the systemic user postgres. Make sure that there is the right amount of privileges for each and every relevant user. General system catalog base tables only 2021-03-07 20:57 MIT License View
171 Privileges to execute routines Find privileges to execute routines that have been given to non-superusers. Check as to whether it conforms to the principle of least privilege. Check that users that correspond to applications have all the necessary privileges. Users (applications) should use a database through virtual data layer. Thus, if they need to modify data in the database (in case of table functions read data), then they must execute a routine.

172 Privileges to use base table columns If you do give privileges to base tables, then these should follow the principle of least privilege - the smallest possible amount of privileges to the smallest possible set of columns General INFORMATION_SCHEMA+system catalog base tables 2020-12-29 10:38 MIT License View
173 Privileges to use base tables Users (applications) should ideally use a database through virtual data layer and thus not directly use base tables. If there is a need to provide direct access to the base tables, then one should grant access based on the principle of least privilege, i.e., to the minimum possible number of base tables.

174 Privileges to use views Find privileges to use views. Check as to whether it conforms to the principle of least privilege. Check that users that correspond to applications have all the necessary privileges. Users (applications) should use a database through virtual data layer. Thus, if they need to read data from a database, then they should use views. General INFORMATION_SCHEMA+system catalog base tables 2020-12-29 10:38 MIT License View

176 Routines that can be invoked with a variable number of arguments Find routines with a VARIADIC parameter. These are routines that take as input an undefined number of arguments where the argument that is an undefined number are all of the same type and are the last input arguments.

177 Routines with the same name and parameters in different schemas Find user-defined routines with the same name and parameters (including the order of parameters) in different schemas. General INFORMATION_SCHEMA+system catalog base tables 2021-10-25 16:11 MIT License View
178 Routines with type casting Make sure that your parameters have appropriate types in order to avoid unnecessary type casting. General INFORMATION_SCHEMA+system catalog base tables 2024-12-19 11:02 MIT License View
179 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
180 Set operations that do not remove duplicate rows in derived tables Find derived tables (views and materialized views) that use a set theoretic operation (union, except or intersect) in a manner that does not remove duplicate rows and thus can produce a multiset not a set. Make sure that it is what is needed. General INFORMATION_SCHEMA+system catalog base tables 2020-12-10 13:32 MIT License View
