I recently noticed the following in the work_mem [1] documentation:

The use of “parallel” here is misleading as this has nothing to do with
parallel query, but
rather several operations in a plan running simultaneously.
The use of parallel in this doc predates parallel query support, which
explains the usage.
I suggest a small doc fix:
“Note that for a complex query, several sort or hash operations might be
running simultaneously;”
Here is a discussion of these terms:

I think "concurrently" is the correct word here.
