Обсуждение: Change the place of the WAL files
Hi here,
I already have an instance with a database. I want to move the WAL files to an other hard disk to have a better speed.
I read that I had to create a symbolic link to do that. Is there another "cleaner" way : an option in the postgres config file??
Thank you,

I.e. the DB has to be shutdown while you do this. I'm sure you know this, but better safe than sorry.
I knew that but thank you to for your advices ;)
