How do i know if a vacuum is running?

Run a query against the "pg_stat_activity" system view (you will need to be
a super-user to view system queries, normal users can only view their own).

To get you started this is the query that I use to spot-check system query
activity:

SELECT procpid, current_query, client_addr, xact_start, query_start

FROM pg_stat_activity

ORDER BY xact_start ASC;
