My primary goal is to get quasi numeric ordering on text column, e.g.

Normal order with varchar would be

You don't need to custom type for that. A custom operator class with
custom comparison operators is enough.
Ok, I tried with ordinary varchar and my own operators/op class. But than:
1) the index is never used (I created it 'with' my opclass)
2) the 'order by' doesn't care about my operator class, it's normal varchar
sequence.
