Hi All,
      I am using Postgres 8.1.9 for my application. My application also has a clean up module which cleans up specified percentage of total database size at regular intervals. Now the problem is I use pg_database_size to obtain the size of the database. After deleting the records, we run Vacuum Analyze to reorder the indexes. The problem here is even though some records are cleared, it still shows the original DB Size. Is there any way to find out the actual DB Size or it would be more useful, if I can get the size of each table.
     I can't run Vacuum Full because the application should be run 24*7 without downtime.

Can someone please help me in solving this.

Please let me know if you need any clarifications.

Thank you,
Venu.
