881User-defined routine execution privilege has been granted to PUBLICYou should follow the principle of least privilege and thus not have in your database user-defined routines that execution privilege is granted to PUBLIC, i.e., to all the database users now and in the future. By default, PostgreSQL gives routine execution privileges to PUBLIC.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-02-25 17:30MIT License
882User-defined routines that have the same name as some system-defined routine.Avoid creating user-defined routines that have the same name as some system-defined routine because it may cause confusion.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-02-25 17:30MIT License
883User-defined routines that use dynamic SQL to execute data manipulation statementsFind user-defined routines that use dynamic SQL to execute data manipulation statements (SELECT, INSERT, UPDATE, DELETE).Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-11-04 12:39MIT License
884User-defined routines that use keyword DECLARE but do not declare anythingFind user-defined routines that use keyword DECLARE but do not declare anything.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-11-05 14:47MIT License
885User-defined routines that use md5 hash for other purposes than generating test dataFind user-defined routines that use md5 hashes for the security purposes. Nowadays such hashes can be calculated too quickly and its use should be avoided at least for hashing passwords. Exclude routines that invoke both md5 function and generate_series function and are thus probably used to generate test data.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-10-31 15:23MIT License
886User-defined routines that use positional references to parametersUse parameter names instead of positional references to improve code evolvability.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-11-05 13:18MIT License
887User-defined routines with dynamic SQL that are potential targets of the SQL injection attackFind routines that have at least one input parameter, use dynamic SQL but do not escape the input arguments at all.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-11-04 11:58MIT License
888Username is not uniqueFind textual columns that potentially contain usernames (including columns that potentially contain e-mail addresses) that do not have a unique constraint or a unique index that involves only this column.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-02-25 17:29MIT License
889Using AFTER triggers to enforce constraintsDo not let the system to do extra work. Checking a constraint with an AFTER trigger means that the trigger procedure will be executed after the data modification and if the check fails, then the system has to do extra work to roll back the changes.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-02-25 17:29MIT License
890Using BEFORE triggers to log data changesDo not let the system to do extra work. Logging changes with a BEFORE trigger means extra work for rolling back the changes in case the logged data modification fails.Problem detectionINFORMATION_SCHEMA+system catalog base tables2021-02-25 17:29MIT License
891Using 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
892Using 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 tables2024-12-21 17:17MIT License
893Using 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.

894Using 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
