  1. Prevent inlining of multiply-referenced CTEs with outer recursive refs.

  2. Allow user control of CTE materialization, and change the default behavior.

  3. Split QTW_EXAMINE_RTES flag into QTW_EXAMINE_RTES_BEFORE/_AFTER.

  4. document when PREPARE uses generic plans

It would certainly be possible to make an explicit NOT MATERIALIZED
override such a choice by the planner, or produce an error if it is
actually impossible to do so (e.g. using NOT MATERIALIZED on a wCTE)
