title: Advantages of using multiple schemas?
body: <p>We are currently developing In Java/Hibernate multiuser application with postgreSQL.And we are migrating our database to multiple schemas (one schema as one company);
  Now i saw this drawback database size is getting more and more even though there the same data:before migrating there were 700MB; after roughly 2GB.</p>
  
  <p>Because of this we are facing backuping/restoring problems it is taking much more than previous one.</p>
  
  <p>Q:it can be avoided wasting time/space for making faster deliverability?
     Or, are we doing something wrong ?</p>
