This adapter provides Postgres 9.5+ backed rule storage.

The adapter relies on a table with the following structure:

• name - A text or varchar column with a unique constraint. The adapter makes heavy use of UPSERT functionality, which relies on unique names.
• rules - A jsonb column where rules will be stored. The use of jsonb and jsonb specific operators means the Postgres version must be 9.5 or greater.

In the likely chance that you're managing a database using Ecto you can create a migration to add the flippant_features table with the following statement (or an equivalent):

CREATE TABLE IF NOT EXISTS flippant_features (
  name varchar(140) NOT NULL CHECK (name <> ''),
  rules jsonb NOT NULL DEFAULT '{}'::jsonb,
  CONSTRAINT unique_name UNIQUE(name)
)

If you prefer you can also use the adapters setup/0 function to create the table automatically.
