Thanks for the reminder! Here is v5. The changes are:
- guc is called temp_file_limit, which seems like the best choice to
- removed code to do with truncating files, as after testing I agree
with you that temp work files don't seem to get truncated.
I have not done anything about the business on units - so we are in KB
still - there is no MB unit avaiable in the code as yet - I'm not sure
we need one at this point, as most folk who use this feature will find
4096GB a big enough *per backend* limit. Obviously it might be a good
investment to plan to have MB, and GB as possible guc units too. Maybe
this could be a separate piece of work since any *other* resource
limiters we add might find it convenient to have these available?
