For what it's worth VACUUM ANALYZE does have to take an additional
lock to update the statistics. It should rarely cause any problems but
it is a possibility.
When you do get a good example you might want to take the contents of
pg_locks at the same time as pg_stat_activity. That would at least be
able to help rule out any real locks and make it clear it's really
stuck on waiting for a block to become unpinned.
