Perhaps the type of a base table column should be an integer type (based on column names) |
Find columns of base tables where the name of the column has prefix or suffix "id" or has the name "id" but the column does not have an integer type or uuid type. A convention is to use the phrase "id" in the names of surrogate key columns. |

Find base table columns that name refers to the possibility that these are used to register XML/JSON values. Find the columns that do not have an appropriate data type (xml, json, jsonb). One shouldn't use columns with a textual type to register such data. |

Perhaps too many different prefixes in the names of database objects that have the same type |
One should be consistent in naming, including in the use of prefixes. If you use prefix in the name of a database object, then it should refer to the type of the database object. Do not use different prefixes in the names of database objects that have the same type. Find types of database objects in case of which there are different prefixes in different names. |

Perhaps unnecessary DECLARE section in a PL/pgSQL routine |
Find PL/pgSQL routines that perhaps unnecessarily contain DECLARE section. More specifically, find routines with the DECLARE section where the only task seems to be raising an exception. The query excludes the cases where the error message is constructed dynamically, i.e., in this case using a variable maybe justifiable. |

Personal names are unique |
Find all primary key and unique constraints of base tables that involve at least one column with personal names. Personal names are not unique and these cannot be (usually) used to guarantee uniqueness. Either one has declared a superkey instead of candidate key (i.e., the key contains a column that is not needed for uniqueness) or the key columns have been found incorrectly. |

PL/pgSQL functions without the RETURN clause |
The return value of a function cannot be left undefined. If control reaches the end of the top-level block of the function without hitting a RETURN statement, a run-time error will occur. This restriction does not apply to functions with output parameters and functions returning void, however. In those cases a RETURN statement is automatically executed if the top-level block finishes. It also does not apply to trigger functions that only task is to raise an exception. |
