parththakkar106andClaude Opus 5 6c38b25439 Say what the vacuum measured, and what SP7 got wrong

The 11 MB the vacuum gave back against a mid-hundreds guess, and the reason:
the heap is 1.7 MB and the rest is TOAST, so a migration touching small
columns bloats the heap and reuses the toast pointers. The rule keeps its
cost estimate rather than its size, and SP8 is the other shape -- it drops
toasted columns, and DROP COLUMN frees nothing until a VACUUM FULL.

And the handover moves to SP9: what a hand-driven SP7 turned out to be wrong
about, the three findings from fixing it, and the fact that the fix itself has
not been driven by hand either.
