No, it's just taking the dead tuples it's got so far and deleting them
from the indexes. It does that whenever it's got VACUUM_MEM worth of
dead tuples collected. You might be able to make things go a little
faster by increasing VACUUM_MEM ... but I wouldn't recommend aborting
the job at this point.

Looks like it's making progress to me.
