If your vendor does not support anything later than 8.2, you should change vendor (and product), if you can. Is there no later version of the product that supports a supported version of PostgreSQL? > any place to check the autovacuum schedule in our existing system? I am not sure what you mean -- if enabled, autovacuum is scheduled according to the parameters mentioned in http://www.postgresql.org/docs/8.2/static/routine-vacuuming.html#AUTOVAC UUM If you want to know when a table was last vacuumed, there's the catalog table pg_stat_all_tables.
