Обсуждение: Deleting old files from pgsql_tmp

Is it safe to delete old files created in pgsql_tmp?  I ask because a
rogue query created almost 800 GB of temporary files and I would like
to reclaim that disk space.  The query was killed (using kill -9 which
I know is not the right thing to do...) so did not get the chance to
clean up after itself.

Yes, as long as the files are not associated with any running backend.
