Those GRANTs are quite unnecessary when the grantee is a superuser.
Superuser roles always pass every privilege check.

Works for me.  For that matter, given the GRANT WITH ADMIN OPTION,
it works even if "ingmar" isn't a superuser.

I'm betting you weren't actually operating as the "ingmar" role
when you did that, but since you didn't show your steps in any
detail, it's hard to say where you went wrong.
