Hello all,
I've got 2 more questions. The cron job is now setup and email gets generated with proper body.

I've one setup with NFS which appears to work smoothly. Now soon, I will be given a Linux VM on a different physical server, but will retain my NFS mount. I've installed Postgres 9.4 using the graphical installer and specified the directory for the nfs mount. 

1) When I move to the new VM, can I keep using that NFS mount without having to do a re-install of PG? This would be a different physical machine. 

2) I have a cron job that deletes log files older than 10 days, but I am noticing rather large log files. Is there a way to limit the size of log files?

users do upserts and they are valid, but those are getting dumped as error statements. I set the verbosity to "terse", but still seeing lots of log output.

My settings are as follows:
postgres=#  select name,setting,unit from pg_settings where name like '%log%';
            name             |            setting             | unit
