b) Restore tables using gpdbrestore from a specified location and create a new database
[gpadmin@sachi ~]$ gpdbrestore -R sachi:/disk4/backup/db_dumps/20150111

20150111:17:31:14:023833 gpdbrestore:sachi:gpadmin-[ERROR]:-gpdbrestore error: Database test1 does not exist and -e option not supplied
Solution:
1. Open gp_cdatabase_1_1_20150111172357 and change the database name to new database test1.
[gpadmin@sachi 20150111]$ cat gp_cdatabase_1_1_20150111172357
--
-- Database creation
--
CREATE DATABASE test1 WITH TEMPLATE = template0 ENCODING = 'UTF8' OWNER = gpadmin;
[gpadmin@sachi 20150111]$
2. use -e option to create the database.
Now run the restore
[gpadmin@sachi ~]$ gpdbrestore -e test1 -R sachi:/disk4/backup/db_dumps/20150111
