Hi,

I have autovacuum running in background from last 30-40 minutes but I
noticed that it is with "(to prevent wraparound)" say for example
autovacuum: VACUUM trk.move (to prevent wraparound).

So what is the meaning of "(to prevent wraparound)" here ?

Will it impact the autovacuum anyhow ?

Please help me.



Regards,
Atul
