Description:        pg_dump doesn't dump expressions with sequence in
DEFAULT setting for some column in table
Details:

I use some expression as DEFAULT setting for some column of some table. For
example, nextval('myseq') * 10.
Then, I pg_dump my database and restore it. I see 'nextval('myseq')' (w/o
'*10').

(Surely, '*10' is just an example, I know, that I can increase the INCREMENT
parameter for the sequence.)

I suppose it's a bug.
