interval type fields not supported

[johanek]

I'm not sure what these should be converted to, but internal isn't a valid type in mysql

$ cat test.pgsql
CREATE TABLE public.dcim_device (
    id uuid NOT NULL,
    created date,
    diff_time interval,
);

$ perl pg2mysql.pl < test.pgsql

DROP DATABASE IF EXISTS public;
CREATE DATABASE public;
CREATE TABLE public.dcim_device (
    `id` varchar(36) NOT NULL,
    `created` date,
    `diff_time` interval,
);
