Re: Autovacuum does not stay turned off

This makes sense.  What queries can I run to see how close to the limit we are?  We need to determine if we should stop the process which updates and inserts into this table until after the critical time this afternoon when we can perform the required maintenance on this table.

You're probably approaching the wraparound limit in some database.  

If you think you can't afford the overhead when users are accessing
the system, when are you vacuuming?

We are changing the table structure tonight.  These two tables are very highly updated.  The goal is to use autovacuum but not have it take 10 days to run on a 13MM record table.
