The list of all the queries

Inconsistency between the type and the default value of a column (time values)

Query goal: Find table columns with time types, which data type and dynamically found default value have a different type.
Notes about the query: The query finds default values that are associated directly with a base table column as well as default values that are specified through a domain. The query does not find default values of domains that are not associated with any table.
Query type: Problem detection (Each row in the result could represent a flaw in the design)
Query reliability: Medium (Medium number of false-positive results)
Query license: MIT License
Fixing suggestion: Decide as to whether it is important to record information about a timezone or not and accordingly change either the type or the default value of the column.
