Hi All, I am also a newbie here! I need to backup a database and restore it into the target machine where the database may already present or might not. If it exists, I want the "restore" command to overwrite, otherwise, just create a new one.
I tried using the commands: (1) BACKUP: pg_dump -h localhost -U username db > dump_file.out; RESTORE: pg_dump -h localhost -U username db < dump_file.out; (2) BACKUP: pg_dump -h localhost -U username -Ft db > dump_file.tar; RESTORE: pg_restore -h localhost -U username -d db dump_file.tar; "Backup" worked perfect in the above 2 scenarios whereas "restore" didn't yield the exact results. For testing it, I took the back-up and intentionally deleted few records in a table. I then restored the database in the same machine where
the database exists. I expected the deleted records to come back as I was restoring the one which has the complete data. It didn't yield proper results. And I wonder why.. I believe I might be doing something marginally wrong. I would appreciate if any geek over here to guide me the "restore" command properly.
Thanks in advance, Siva. ::DISCLAIMER:: ----------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
