Possible, since I didn't have test coverage for either of those 2 commands.

That makes a lot of sense, but it might spoil things for the
pg_stat_statements.track = 'top' + pg_stat_statements.track_utility =
'on' case. At the very least, it's a POLA violation, to the extent
that if you were going to do this, you might mandate that nested
statements be tracked along with utility statements (probably while
defaulting to having both off, which would be a change).

Since you've already removed the intoClause chunk, I'm not sure how
far underway the review effort is - would you like me to produce a new
revision, or is that unnecessary?
