This bit does not make much sense to me. A transaction waiting will not
show up in the log. Were they cancelled? Can you paste an extract from
the log?

Do you have a vacuum in cron or something like that? As Tom says, if it
had been autovacuum, it should have been cancelled automatically (else
we've got a bug); but something invoking vacuum externally wouldn't
have, so what you describe is what we would expect.
