One more thing --- there was talk of moving some of this into chapter
66, but as someone already mentioned, there are no subsections there
because it is a dedicated topic:
66. How the Planner Uses Statistics.
I am not inclined to add a prepare-only section to that chapter. On the
other hand, the issues described apply to PREPARE and to protocol-level
prepare, so having it in PREPARE also seems illogical. However, I am
inclined to leave it in PREPARE until we are ready to move all of this
to chapter 66.
Actually, 66.1 exists - Row Estimation ExamplesWe should create 66.2 - e.g. Statistics of Parameterized Plans
My point was 66. How the Planner Uses Statistics doesn't have a table of contents. I suspect it will if we add 66.2. But, should it have one now, when the only section is 66.1?
The wording improvement are good; but my recommended split between the SQL command section and 66.2 still applies.
