In above case, You can see the error message `role “john” does not exist`. It means that database has been backed up from another PC having name is ‘john’.

So now, in this case there are two solutions to restore this database as follows.

1) Either you can open dump file, and change the role name wherever you find name ‘john’ as your role displayed in following screen. Here I have changed name as ‘navrang’ in place of ‘john’.

2) Another option is, if dump file is too long to change role/owner name, then you can create a user in your PC named ‘john’ so it will work as it is.

And this way we can restore our database.
