Entity Generation breaking with Postgres enum columns when --tables or --skip-tables is specified

[bencpeters]

When I run the model generation on a Postgres DB with a custom enum-based column, I'm getting an error if I try to limit the tables using either --tables or --skip-tables. Model generation works fine if I omit these options.

This is the error:

[9:59:57 AM] Starting creation of model classes.
Unknown ARRAY column type: _volunteer_type_enum table name: users column name: volunteer_type
Error occurred in typeorm-model-generator.

volunteer_type is a simple custom enum:

CREATE TYPE public.volunteer_type_enum AS ENUM (
    'MENTORING_ORGANIZATIONS',
    'MENTORING_STUDENTS',
    'VOLUNTEERING_PROJECT_BASED',
    'VOLUNTEERING_TASK_BASED'
);

CREATE TABLE public.users (
   -- other fields
   volunteer_type public.volunteer_type_enum[]
);
