I'm confused. Maybe I'm missing something, but there is "custom" type in this file:
```
-- subscripting.sql
CREATE TYPE custom (
internallength = 8,
input = custom_in,
output = custom_out,
subscripting = custom_subscript_parse
);
```
```
> \i subscripting.sql
psql:subscripting.sql:39: NOTICE: 42704: type "custom" is not yet defined

```
So the only problem I see is notification about "type 'custom' is not yet defined", but it's the same for "complex" tutorial
```

psql:complex.sql:39: NOTICE: 42704: type "complex" is not yet defined

...
```
Can you clarify this point?
