Sorry about the delay.

Your patch seems reasonable, but I thought we'd also want to change
"per session" to "per session (with an additional temp_file_limit
allowance within each parallel worker)" for temp_file_limit.

I think it's worthwhile noting this for temp_file_limit specifically,
since it's explicitly a per session limit, whereas users are quite
used to the idea that work_mem might be doled out multiple times for
multiple executor nodes.
