I'm pretty sure that nobody involved noticed the impact on VACUUM
ANALYZE command; all discussion was around autovacuum impact; and
Jan argued that this was leaving things in a status quo for that,
so I conceded the point and left it for a follow-on patch if
someone felt the behavior needed to change. Sorry for the miss.

As far as I'm concerned all effects on the explicit command were
unintended and should be reverted.
