Description of change

Currently when dealing with an array of enum using the Postgres dialect, Sequelize generates an invalid enumeration cast key while inserting data.

Related issue (I think): #4048

DDL of the table:

create table "Table"
(
    id uuid not null constraint "Table_pkey" primary key,
    "createdAt"      timestamp with time zone         not null,
    "updatedAt"      timestamp with time zone         not null,
    "deletedAt"      timestamp with time zone,
    column           "enum_Table_column"[] not null
);

DDL of the type

create type "enum_Table_column" as enum ('Value1', 'Value2', 'Value3');

Then while inserting data here's the cast key generated by sequelize:

array['Value1']::"enum_public.Table_Column"[]

The correct cast key should be:

array['Value1']::"enum_Table_Column"[]

This pr fixes this issue.

@codemers Can you look into the tests and rebase your branch?

Is this by any chance the same as #13807 ?

Yes, this is the same issue, but the PR here only works for public as is not passing the schema if its redefined, the #13807 fix handle both scenarios, when is using the public/empty schema, that both:
"enum_my_enum"[] and "public"."enum_my_enum"[] works
and the scenario where schemas are needed like:
"my_schema"."enum_my_enum"[]

@codemers try the current main branch (merged today) code to confirm the issue is fixed for you, but I think it is.

@codemers 6.12.2 was just released with a fix for this issue. Please try that version and if it works this bug can be probably closed.
