761Using conditionals to determine the returned valueUse SQL language instead of PL/pgSQL where possible. Instead of using an IF statement, you can check as to whether the data modification succeeded or not by using the RETURNING clause in the data modification statement.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-11-04 11:52MIT License
762Using in some way reserved (in PostgreSQL) SQL keywords as the names of a database object (aggregate view)"Names in software are 90 percent of what make software readable. You need to take the time to choose them wisely and keep them relevant. Names are too important to treat carelessly. Names should not cause confusion." (Robert C. Martin, Clean Code) Names should not cause confusion. Find the distinct names (identifiers) of user-defined objects that are SQL keywords that are not completely unreserved in PostgreSQL, i.e., these either never cannot be used as regular identifiers or cannot be used in case of some type of database objects. In PostgreSQL "there are several different classes of tokens ranging from those that can never be used as an identifier to those that have absolutely no special status in the parser as compared to an ordinary identifier. " (PostgreSQL manual) Moreover, such identifiers are often too general, i.e., do not provide enough information about the named object.Problem detectionINFORMATION_SCHEMA+system catalog base tables2023-03-17 11:19MIT License
763Using in some way reserved (in PostgreSQL) SQL keywords as the names of a database object (detailed view)"Names in software are 90 percent of what make software readable. You need to take the time to choose them wisely and keep them relevant. Names are too important to treat carelessly. Names should not cause confusion." (Robert C.

764Using routine name in front of a parameter name in a routine body to refer to the parameter of the routineWrite code that is easy to understand and not unnecessarily long. A routine cannot have two or more parameters with the same name. In this case using longer identifier in the form routine_name.parameter name is unnecessary.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-11-05 13:40MIT License

Moreover, such identifiers are often too general, i.e., do not provide enough information about the named object.

767Validation method does not confirmFind user-defined SQL and PL/pgSQL routines that do not return a value although the name suggest that it should return a value (starts with "validate" or "check").Problem detectionINFORMATION_SCHEMA+system catalog base tables2023-01-06 14:25MIT License

769Views without security barrierFind views that do not have the security barrier option.Problem detectionINFORMATION_SCHEMA+system catalog base tables2023-11-22 12:05MIT License
770Views with unnecessary security invokerFind views with security invoker option that do not have any underlying base table with a security policy. Security invoker option of views is possible starting from PostgreSQL 15. "The main use case (and the one that inspired the feature) is to be able to use views and still check row-level security policies on the underlying tables as the invoker."Problem detectionINFORMATION_SCHEMA+system catalog base tables2023-11-17 18:39MIT License

772Wrong comment - trigger function does not implement a database operationTrigger functions should not contain references to database operations. Perhaps the trigger implements ensuring some invariant of the operation but it does not implement the operation itself.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-02-25 17:30MIT License
773YELLING IN COMMENTS!Find comments of derived tables and routines that consist of only uppercase letters. Do not use only uppercase (capital) letters in order to write comments.
