Moving pg_xlog folder

[Wei Shan <weishan.ang@xxxxxxxxx>]

Hi all,

OS: CentOS

PG version: 9.3

I'm testing the scenario of moving the xlog folder to a fast pair of disk. This was the steps I followed;

1. create new mountpoint with the correct permissions

2. Shutdown DB

3. Create softlink from new mountpoint to $PG_DATA/pg_xlog

4. Startup DB

However, after I start the DB, I hit the following error;

-bash-4.1$ psql

psql: could not connect to server: No such file or directory

Is the server running locally and accepting

connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

This issue resolves by itself once I reboot the server after I move the XLOG. Any ideas what I did wrongly?

Thanks!
