What I can recall being discussed in the past is to extend
EXPLAIN and/or EXPLAIN ANALYZE to cover utility statements
that have nontrivial execution complexity --- for example,
ALTER TABLE has a lot of machinery underneath, and people
often wish to know things like whether a particular ALTER
will cause a table rewrite or not.
Of course, a patch for that would be a few orders of magnitude
larger than what you've got here :-(. But if you're looking
for a framework for reporting these sorts of details, I'd
much rather go in that direction than follow the model of
VACUUM VERBOSE. VACUUM VERBOSE is a kluge with little to
recommend it other than having been easy to implement.
