Then I would pick PREFIX-master... But then I would hate having a pcmk-master
process :(

Maybe all the logging information should be handled by one process so
syslog/journald/stderr are happy?

Despite it's multiprocess architecture, PostgreSQL either:

* emit to syslog/journald using the same ident for all process
* capture stderr of all process and redirect to one file.

oh ok, sorry.

I just finished a day reading log file /var/log/pacemaker.log on a Suse 12 SP1
that was packed with XML diffs :/

Maybe I should have checked /var/log/messages or the syslog setup...

But honestly, I hate having mixed logs all packed in one same files
like /var/log/messages :/

Sure, but a simple info messages explaining that «the CIB has been updated by
tool "<tool_here>" » sound enough to me.

And this can go to detail/debug logs I suppose.
