I did regression tests (make check-world) and 
checked manually pg_dump --on-conflict-do-nothing works properly.
Also it seems to me the code has no problem.
This feature has advantage to some users with small code change.

So I marked it as 'Ready for committer'.
I'd like to wait and see committers opinions.
