SHOW EXPLAIN UPDATE/DELETE
- Introduce "Query Plan Footprints" (abbrev. QPFs)
QPF is a part of query plan that is
1. sufficient to produce EXPLAIN output,
2. can be used to produce EXPLAIN output even after its subquery/union
was executed and deleted
3. is cheap to save so that we can always save query plans
- This patch doesn't fully address #2, we make/save strings for
a number of EXPLAIN's columns. This will be fixed.
