But, have same problem. It is almost 1 hour now, the restoration is still going on. After every test case execution, we would like to refresh the database and expected refresh should be completed in less than 10 minutes. Is this achievable with the kind of configuration I have listed in my earlier email. Kindly help , as how to speed up this restoration process.

I tried to use pg_restore to restore this dump, but it takes hours to restore the dump. I have used the configurations parameters as below:
