Serial is no datatype, but an int4 with a default. I don't know if the 
default is reverse engineered correctly, I'd recommend to change it 
manually to "serial".

Probably not. pgAdmin has special treatment for int4/default to detect a 
serial; PD as cross platform tool is not smart enough.
Similar about inheritance; I don't even know a way how to design this in 
PD (in PD 8.0, I doubt 10.x is better).

You could try ERwin, but I doubt you will be luckier there.
