PostgreSQL Query Catalog

Project on GitHub
Filter Queries

Found 1036 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.

441 Names of database objects (regular identifiers) that contain $ Find names (identifiers) of user-defined database objects that are regular identifiers and contain the $ sign starting from the second position. "Note that dollar signs are not allowed in identifiers according to the letter of the SQL standard, so their use might render applications less portable."

442 Perhaps check constraint names contain incorrect or unnecessary words Find names of check constraints (either associated with a base table or a domain) that names contain words that are not needed in the name. For instance, constraints cannot ensure the correctness of data and thus the word correct should not be used in the names. Words like "valid" or phrases like "follows_rules" are just noise because all the constraint ensure that the registered data values are valid and follow certain rules.

443 Names of the password columns Find names of columns of base tables, views, and materialized views that contain passwords. Make sure that the naming is consistent, General INFORMATION_SCHEMA+system catalog base tables 2025-11-07 10:11 MIT License View
444 Names of database objects that contain dollar sign Find names of database objects that contain a dollar sign ($) that is not the first symbol of the name. In PostgreSQL regular identifiers cannot start with $. However, $ can be used in other positions of the name.

449 Names of database objects with perhaps too many subcomponents (terms) that consist of only consonants Find names of database objects where the number of subcomponents (terms) that consist of only consonants is bigger than the number of subcomponents that contain at least one vowel.

451 Too short domain constraint names Find names of domain constraints that are shorter than the length of the name of the domain + two characters. Problem detection INFORMATION_SCHEMA only 2025-11-07 10:11 MIT License View
452 Domain name contains base table name Find names of domains that contain the name of the table that column the domain specifies. Domains are reusable artifacts that one should be able to use in case of different base tables. Thus, it is inappropriate to use the name of a particular table in the name of the domain.

453 Constraints with the same name within the same schema and constraint type Find names of foreign key constraints that are used within the same schema more than once. Find names of check constraints that are used within the same schema more than once. Find names of constraint triggers that are used within the same schema more than once. 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.

458 Perhaps is not snake_case - long subsections without underscores Find names that perhaps do not use the snake_case naming style because the name contains a long subsection (at least 20 characters) without underscores.

459 Perhaps is not snake_case - id, code, key, or nr is not preceded by an underscore Find names that perhaps do not use the snake_case naming style because the name ends with the phrase "id", "uuid", "code", "kood", "key", or "nr" that is not preceded by an underscore.
