Support for uuid and CHARACTER varying[] in Postgres database

[GeekEast]

• for DDL like this:

  create table companies
  (
  id                  uuid                default public.uuid_generate_v4() not null   constraint clients_pkey
  tags                character varying[] default '{}'::character varying[],
  deleted_by_id       uuid,
  created_by_id       uuid,
  );

• gen outputs errors like:

  table: companies unable to generate struct field: id type: UUID error: unknown sql type: uuid
  table: companies unable to generate struct field: tags type: _VARCHAR error: unknown sql type: _varchar
  table: companies unable to generate struct field: deleted_by_id type: UUID error: unknown sql type: uuid
  table: companies unable to generate struct field: created_by_id type: UUID error: unknown sql type: uuid

  Issues

• It seems like gen doesn't support the uuid type
• It seems like gen doesn't support the CHARACTER Varying[] type

[GeekEast]

Suggestion

• for uuid, suggest to generate type as uuid.NullUUID
• for CHARACTER varying

  type Company struct {
  Tags sql.NullString `gorm:"column:tags;type:VARCHAR;default:'{}';" json:"tags"`
  }

@GeekEast I added uuid support for postgres handling it as a string - Looking into CHARACTER varying

[dwgeneral]

CREATE TABLE order_details (
    order_id smallint NOT NULL,
    product_id smallint NOT NULL,
    unit_price real NOT NULL,
    quantity smallint NOT NULL,
    discount real NOT NULL
);

It seems like gen doesn't support the real type of Postgresql

table: order_details unable to generate struct field: unit_price type: FLOAT4 error: unknown sql type: float4
table: order_details unable to generate struct field: discount type: FLOAT4 error: unknown sql type: float4
