Hi! I can reproduce the problem on my notebook, where I don't have any hurry of working around the issue. The output of ipcs:

(I'm quite sure I did not set this parameter by hand). I now worked around the problem by commenting out the shared_memory line, but it would be great of pg_upgradecluster would refuse to upgrade if the upgrade is going to end up with this error message and print a clear explanation what shared_buffer should be set to (or it should recommend to comment out the shared_buffer value if the default is sane) WM -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
