Use PostgreSQL's catalog views to return the columns of cards, their declared types, whether they accept NULL, and their defaults, in ordinal order. Do not read seed/01-schema.sql to manufacture the output.
Expected: 6 rows. id is an integer identity, balance is numeric(10,2) and non-null with a zero default, status is card_status and non-null with an active default, registered_at is timestamp with time zone, and deleted is boolean with a false default. The result should describe the database you connected to.
