| 466 | Inconsistent names of database objects that are used to manage the state of main objects in the database | "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) The naming must be consistent. One should avoid mixing synonyms like "seisund", "staatus", and "olek" in Estonian or "state" and "status" in English and stick with one term. For instance, it is a bad practice to use word "state" in table names but word "status" in function names. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-03-18 17:13 | MIT License | |
| 467 | Inconsistent naming of columns with BOOLEAN type | Find as to whether some columns with the type Boolean start with a prefix ("is", "has", "can", "on") and some do not. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-01-03 09:54 | MIT License | |
| 468 | Inconsistent naming of comment columns | Find columns of tables that start with the word comment or komment but end differently (excluding numbers). Return result only if there is more than one naming variant of such columns in the database. For instance, a column has the name "comment" but another "comments". | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2022-11-15 14:09 | MIT License | |

| 470 | Inconsistent referencing to character classes | Find as to whether regular expressions use inconsistently references to character classes: [^\s], [^\d], [^\w], [^[:space:]], [^[:digit:]], [^[:word:]] vs [^\S], [^\D], [^\W]. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-09 12:02 | MIT License | |

| 475 | Inconsistent use of casting syntax in routines | Find as to whether PL/pgSQL routines and SQL routines that do not have SQL-standard body use different syntax for casting (cast function vs :: operator). | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-10-29 11:33 | MIT License | |
| 476 | Inconsistent use of functions and procedures | Find as to whether the database has both procedures as well as functions that do not return a value (i.e., return VOID). Such routines are generally used to modify data in the database.
