Hi Ron,
Thanks!!
I tried to grep all the process owned by postgres as well, but got same results. No other process are active other than two threads of pg_upgrade. Thanks,
Sohel

Hi,
I am trying to upgrade my postgresql database from version 9.1 to 9.6 using pg_upgrade utility.
I have started this activity with 6 threads and running with no issues but I can see only 2 active threads of pg_upgrade when checked on OS using "ps -ef| grep pg_upgrade" which might slow down my upgrade process.
Is there any limit of adding jobs in "-j" parameter in pg_upgrade utility?
Or is there any settings that I need to configure in postgresql.conf file?
Below are the configuration of my server:
OS : Amazon Linux
RAM: 64GB
CPU: 16
DB size : 5 TB
Upgrade utility : pg_upgrade
Jobs: 6
Issue : only 2 threads of pg_upgrade are active
Appreciate your help!!
Thanks,
Sohel
