It seems that these temp files are the result of normal query execution
(and will be cleared when query finishes).

Have you tried enabling log_temp_files and check what query generates these
temp files?
It is a very common situation when a single badly written query generates
hundred gigabytes of temp files until the end of disk space.
Alternatively, you can try enabling temp_file_limit to limit the maximum
size of temp files per query.

Kind regards,
