BTW on ubuntu and debian i never use pg_ctl directly, postgresql-common has a very nice CLI for this.
For the restart i used: sudo pg_ctlcluster --force 9.4 main restart
Thanks for all the good advice!

It's just a directory scan and an unlink() for each file that has the right filename pattern to be a temp file. If you've got a reasonable filesystem I wouldn't expect it to take long. Maybe a minute? (but don't quote me on that)
