I'm breaking out a few questions I'd posed on another thread about the release timeline [1] into this new thread.
I noticed on the PG13 release announcement that the link for incremental sort goes to the GUC docs [2] because (as Jonathan Katz confirmed in the linked thread) that page actually has helpful anchor tags. But I'm wondering if instead/also it should point to the examples in the EXPLAIN docs [3] which actually explain what incremental sort does. In the initial patch discussion we ended up putting the explanation there because there was a desire to keep the GUC descriptions short. But that raises a larger question: should the GUC page also link to the EXPLAIN examples? There's not an obvious anchor tag on the page (that I can tell) to use for such a link though...so that could get into an ever larger question about adding those anchors. It seems to me that we don't have a particularly great place for detail explanations in the docs of the algorithms/nodes/etc. we use...unless the new glossary section in the docs could fill that role? Any thoughts?
