I never said I kill -9 . I do pg_ctl stop
BTW, drop cascade on the namespace seems to be working.

create temp queries failed with an error asking to increase
max_locks_per_transaction variable. Now that you mention about
the clean up code, it does make sense - it was probably trying to
cleanup and it couldn't.
I increased max_locks_per_transaction and now delete cascade seems to work
(still running, so I can't say)

Didn't know that - thanks for the info.
