Hi,
I recently noticed the following in the work_mem [1] documentation:
“Note that for a complex query, several sort or hash operations might be running in parallel;”
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;”
This should also be backpatched to all supported versions docs.
Thoughts?
Regards,
