begin
  insert into public.profiles (id,first_name,last_name)
  values (new.id,new.raw_user_meta_data->> 'first_name',new.raw_user_meta_data->> 'last_name');
  return new;
end;

i have this function work when a new row added in users table It is creating a new row in the profiles table, and i want to make this function to check if the `raw_user_meta_data `have only `first_name `and

last_name

And they are not null and if the user pass other data in

raw_user_meta_data
