#4244 There's error message in postgresql log when use pgsqlsetup to setup xcat database

[Degao Chu]

After install xcat and postgresql, use command "source /etc/profile.d/xcat.sh;/opt/xcat/bin/pgsqlsetup -i -V 2>&1 >>/tmp/pcm-pgsqlsetup.log" to setup postgresql. There will be some error message in postgresql log. Seems no function impact. We don't know whether it's a bug. Please help investigate it.

This has nothing to do with xCAT. autovaccum is a function of postgresql and it may have some issue in your environment. Is this Redhat 7, what level of postgresql. Are you using the one shipped with the OS?? I would search for this error out of postgresql in the autovacuum area.
What level of xCAT are you running.
