Hi Scott,
Thanks for replying. The tablespace is not the main problem here. I
want the data files to grow in the new partition along with the old linux
partition.
Let me put like this.
We have a linux partition of 120GB called as
/local/postgres/database/Data/< followed by all files>
This /local partition is 95 % used.
So we are adding one more partition called /local1 which is
approximately 250 GB. Now I want to inform postgres that after /local
partiion is 100 %, I want to utilize the /local1 so that the database can
grow significantly. In other words, the data file created and maintained by
postgres will grow in the /local1 partition.
How to do this in postgres?
I don't want to compare with Oracle. But in Oracle, when we create the
DB
we will tell alter database add data file
'/local/postgres/database/data'
then if /local partition is full, we can add another data file such as
alter database <db Name> add data file '/local1/data2'
Is there a similar way or equivalent way to do in postgres?

So,
alter table ... set tablespace new_tablespace
doesn't work for you in this circumstance?
