Re: how to add a new data partition

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  add data file '/local1/data2'

    Is there a similar way or equivalent way to do in postgres?

Regards
skarthi
