Subject: [GENERAL] HELP: Urgent, Vacuum problem

Hello,
 
I'm having a major Vacuuming problem.  I used to do a full vacuum every morning on my postgres database to clean up empty space on a table but because of it's size, the locking of the database causes my application server to max out the database connections and causes database errors.  To fix that problem, I have turned off the full vacuum and are just doing a standard analyze vacuum.  No I'm getting very close to running out of space on my disks because the table keeps on growing and the database is not re-using deleted record space.  I know this because I delete 99% of the records from the table after I have exported them but the size of the database tables are not decreasing.  Now I can't shrink the size of the tables because the full vacuum takes too long to run  Over 2 hours and locks the table for too long.
 
Can anyone help me with fixing my problem with vacuuming and disk space?
 
I'm using version 7.4.2 on solaris.
 
Thank you,
 
 
Steve.
