Are these happening regularly?  They indicate that something is
happening on the table that collides with what autovacuum needs to do,
and autovacuum defers its task.  For this to happen you need to be doing
ALTER TABLE or similar however; normal UPDATE/INSERT/DELETE should not
cause autovacuum to cancel itself.
