One option if you can have the DB offline for a little while:
1) Shutdown Postgres
2) Move your current data directory to the new partition
3) Update your PGDATA variable, and any scripts that reference it to reflect
the new data path. You might also like to symlink the old data dir to the
new one.
4) Restart Postgres. pg_ctl -D /new/path/to/data start
That's worked for me several time before.

Subject: [ADMIN] how to add a new data partition
Hi all,
We are using postgres 8.0.1 on our production and 8.2 on our development.
The linuix partition is getting full where the database resides. In few
weeks our partition will ran out of space so the database will also run out
of space. We have added another HDD of 300GB. Now my question is, how will
I point the database to the new partition along with the old one. Do I need
to create a symbolic link to the exitisting DB?
Adding a new tablespace doesn't solve the issue as there are many tables
in the old tablespace. Is there a way to extend the tablespace to the new
partition like in Oracle.
Did anybody faced this problem and how did you resolve. Please share your
thoughts.
Regards
skarthi
