In which state do we need to put the db? We can use both types of backup
strategy. We can pg_dump the table and copy the tablespace folder along
with anyhting else that we may need.

Well, if you do pg_dump - that data will be there.
If you do copy of data directory, that isn't going to work, unless you
put db in proper state.
if you do that, you need to copy pg_xlog directory with it.
So you have to specify which backup strategy you are going to use.
