Обсуждение: Database size

I have recently inherited a Postgres 7.2 DB.  I noticed that the size of the database on the disk is about 100 times
thesize of the nightly dumps that get done.  I looked into it and realized that after millions of rows are deleted each
monththere was no vacuum full performed on the DB.  I also noticed that the disk space was not recovered to the OS.  I
assumedthat was because there was no vacuum full being performed.  I am currently performing a vacuum full and noticing
thatno space is being recovered.  Is it normal for a DB to be that much bigger than it's dumps? 

Thanks,
