Gorm uuid columns default to text

The long and short of it is that gorm only seems to respect uuid columns if they're primary keys, in all other cases, it creates and/or migrates to text instead.

type UserToken struct {
    UUID    string    `gorm:"primary_key;type:uuid;default:public.uuid_generate_v4()"`
}

results in

       Column       |           Type           |              Modifiers              
--------------------+--------------------------+-------------------------------------
 uuid               | uuid                     | not null default uuid_generate_v4()

as you would expect, but

type UserTokenCompany struct {
    CompanyGUID     string    `gorm:"index:idx_company_guid_user_token_uuid,unique"`
    UserTokenUUID   uuid.UUID `gorm:"index:idx_company_guid_user_token_uuid,unique"`
}

or

type UserTokenCompany struct {
    CompanyGUID     string `gorm:"index:idx_company_guid_user_token_uuid,unique"`
    UserTokenUUID   string `gorm:"index:idx_company_guid_user_token_uuid,unique;type:uuid"`
}

both result in Migrator().CreateTable() and AutoMigrate() producing Column | Type | Modifiers --------------------------+------+----------- company_guid | text | not null user_token_uuid | text | not null which unsurprisingly breaks joins and foreign keys.

This appears to be the case on both v1.24.1 and v1.24.3.
