How do I describe an enumeration column in a Rails 3 migration?

Answer 1

You can describe an enumeration column with:

t.column 'role', 'user_role'

I created the enum type with:

execute "CREATE TYPE user_role AS ENUM ('consultant', 'admin');"

Inspecting the database:

    Column     |          Type          | Modifiers | Storage  | Stats target | Description
---------------+------------------------+-----------+----------+--------------+-------------
 role          | user_role              |           | plain    |              |
