Basics
This check is disabled by default.

This check has a base priority of high and works with any version of Elixir.
Explanation
Ensures that Ecto migrations use :text rather than :string for column types.
In modern versions of Postgres, there is no storage or performance benefit to using textual columns with a fixed maximum length, so it is almost always preferable to not set a maximum length in the database and instead enforce max length as a business rule at the application level.
