Thread: Changing WAL Directory in Postgres

Hi all,

 From the last 2 days I am researching on Performance Tuning in Postgres.

For this , I have to change my WAL directory to other disk than the data
directory. But I am not able to find the correct way to do this.

Please be kind to advice.


Thanks & Regards

instead, I would create the databases on another tablespace on a
different volume.

in short:

sudo su - postgres
pg_ctl stop -m fast
cd $PGDATA
mv pg_xlog /another/device
ln -s /another/device/pg_xlog .
pg_ctl start
