What am I doing wrong when defining my primary key here? column: ``` const customPrimaryKey = customType<{ data: number; notNull: true; default: true; }>({ dataType() { return `id bigint generated always as identity primary key`; }, }); ``` Generated SQL: ``` CREATE TABLE IF NOT EXISTS "users" ( "id" "bigint generated always as identity primary key", ``` Error: ``` error: type "bigint generated always as identity primary key" does not exist ```
