PostgreSQL Query Catalog

Project on GitHub
Filter Queries

Found 1018 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.

461 Incorrect specification of logical or in regular expressions Find the use of regular expressions where logical or is incorrectly specified, i.e., (| or |). Problem detection INFORMATION_SCHEMA+system catalog base tables 2025-11-07 10:11 MIT License View
462 Incorrect suffix of a constraint name or an index name If the name of an object has the suffix that refers to the type of the object (for instance, primary key constraint or foreign key constraint), then you should use references to the correct object type. Find suffixes of constraint names and index names that incorrectly refer to the type of the object. For instance, incorrect would be to use _chk as the suffix of an index name or _pk as the suffix of a check constraint name.

463 Incorrect use of non-deterministic functions in CHECK constraints Do not create a constraint in case of which data that satisfied a constraint c at the registration time suddenly does not satisfy it any more as the time goes by. Find all the check constraints that use non-deterministic functions (now, current_timestamp, localtimestamp, current_date, current_time) in a way that makes this situation possible. Fort instance, localtimestamp(0)>end_date is an example of such constraint. Problem detection INFORMATION_SCHEMA only 2025-11-07 10:11 MIT License View
464 INFORMATION_SCHEMA is missing Make sure that you do not drop INFORMATION_SCHEMA schema. In this case most of the design checking queries will not work. This schema automatically exists in all databases. Problem detection INFORMATION_SCHEMA+system catalog base tables 2025-11-07 10:11 MIT License View
465 Initially deferred constraint triggers with unnecessary locking Initially deferred constraint triggers do not need explicit statements for locking tables or rows. Problem detection INFORMATION_SCHEMA+system catalog base tables 2025-11-07 10:11 MIT License View
466 Input parameters that names do not follow the convention to start with _ or p_ For the sake of making code better understandable follow naming conventions. Problem detection INFORMATION_SCHEMA+system catalog base tables 2025-11-07 10:11 MIT License View
467 Input parameters with the same name have different types Find named input parameters of routines that have the same name but different type. It could be a mistake or deliberate due to overloading of routines. Problem detection INFORMATION_SCHEMA+system catalog base tables 2025-11-07 10:11 MIT License View
468 Installed extensions Try to use as much the possibilities of the DBMS as possible. On the other hand, do not install extensions that are not needed in order not to overcomplicate the database. General system catalog base tables only 2025-11-07 10:11 MIT License View

470 Insufficient number of user-defined domains There must be at least n (one in this case) user-defined domains in the database each of that must be used in case of at least two columns of base tables. Problem detection INFORMATION_SCHEMA only 2025-11-07 10:11 MIT License View

473 Insufficient number of user-defined triggers+rules There must be user-defined triggers and/or rules for at least n (three in this case) tasks in the database.

479 Invalid use of the case insensitive search modifier in regular expressions Find regular expression patterns that use (?i) modifier in any other place than at the beginning of the pattern or (?-i) in any place of the pattern. Such use of the modifiers is not supported by PostgreSQL. Problem detection INFORMATION_SCHEMA+system catalog base tables 2025-11-07 10:11 MIT License View
480 Invocation of a system-defined routine without providing any arguments Find user-defined routines that contain an invocation of a system-defined function without providing any argument.
