You need to use DB.extension :pg_array, :pg_inet, :pg_json, not Sequel.extension :pg_array, :pg_inet, :pg_json. Otherwise you are just requiring the files without modifying the configuration for the Sequel::Database instance.
DB.extension :pg_array, :pg_inet, :pg_json
Sequel.extension :pg_array, :pg_inet, :pg_json
