Ok, now I'm officially confused :)
Is it a bug that there's no error or warning or is it a bug that it
ignores the default? Ok, I just found it:
---
In the current implementation, default and constraint clauses for the new
column will be ignored. You can use the SET DEFAULT form of
ALTER TABLE to set the default later. (You will also have to update the
already existing rows to the new default value, using UPDATE.)

Thanks!
