array type insertion failing

A table created with a column which is an Array type does not seem to work with insertions. This PR shows a simple example of what can trigger this, (tested it manually on postgres).

Here is an error message i got on a minimal table setup:

\d people
                              Table "public.people"
   Column   |  Type  | Collation | Nullable |              Default               
------------+--------+-----------+----------+------------------------------------
 id         | bigint |           | not null | nextval('people_id_seq'::regclass)
 first_name | text   |           |          | 
 last_name  | text   |           |          | 
 names      | text[] |           |          | 

ERROR:  malformed array literal: "John" from GORM:
DETAIL:  Array value must start with "{" or dimension information.
STATEMENT:  INSERT INTO "people" ("first_name","last_name","names") VALUES ($1,$2,($3)) RETURNING "id"

GORM sent: INSERT INTO "people" ("first_name","last_name","names") VALUES ('John','Doe',('John')) RETURNING "id"

You can correct this in one way by using curly braces around the array:

The correct way to insert:

INSERT INTO "people" ("first_name", "last_name", "names") 
VALUES ('John', 'Doe', '{"John"}');

Example of failure:

INSERT INTO "people" ("first_name", "last_name", "names") 
VALUES ('John', 'Doe', '("John")');
ERROR:  malformed array literal: "("John")"
LINE 2: VALUES ('John', 'Doe', '("John")');
                               ^
DETAIL:  Array value must start with "{" or dimension information.

ps:

Since it does not work with insertions, unable to confirm whether this works for other operations, I would expect arrays to work though.
