@spec run(include: Keyword.t(atom()), exclude: Keyword.t(atom())) :: :ok

Adds raw SQL queries to a migration for creating the database types, associated functions, casts, operators, and operator families.

This migration includes all migrations under the Pg Types, Pg Operators, Pg Operator Classes, Pg Functions, Pg Private Functions, headings, and Pg Casts

Safe to run multiple times when new functionality is added in updates to this library. Existing values will be skipped.

Individual migration functions return raw sql commands in an {up_command, down_command} tuple.

Configuring Database Objects

To change where supporting functions are created, add the following to your Repo configuration:

config :vtc, Vtc.Test.Support.Repo,
  adapter: Ecto.Adapters.Postgres,
  ...
  vtc: [
    rational: [
      functions_schema: :rational,
      functions_prefix: "rational"
    ]
  ]

Option definitions are as follows:

• functions_schema: The postgres schema to store rational-related custom functions.

• functions_prefix: A prefix to add before all functions. Defaults to "rational" for any function created in the :public schema, and "" otherwise.
