The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/16/parallel-plans.html Description:
In section 15.3.4, I believe "multiple results sets" is a typo for "multiple result sets". It says: > Plans that involve appending multiple results sets can therefore achieve coarse-grained parallelism even when efficient partial plans are not available. It's also possible this should say "multiple results" rather than "multiple result sets". I'm unsure what exactly this sentence is trying to communicate, possibly because I'm only learning Postgres (by reading the docs), and I don't understand what partial and non-partial children mean from the previous sentences in the context of this section. (Perhaps that should also be improved on? Unless it was already explained previously and I've merely forgotten, but I couldn't find that phrasing elsewhere in the documentation.)
