Tomas Vondra cd91de0d17 Remove temporary files after backend crash ... After a crash of a backend using temporary files, the files used to be left behind, on the basis that it might be useful for debugging. But we don't have any reports of anyone actually doing that, and it means the disk usage may grow over time due to repeated backend failures (possibly even hitting ENOSPC). So this behavior is a bit unfortunate, and fixing it required either manual cleanup (deleting files, which is error-prone) or restart of the instance (i.e. service disruption). This implements automatic cleanup of temporary files, controled by a new GUC remove_temp_files_after_crash. By default the files are removed, but it can be disabled to restore the old behavior if needed.
