NetWorker: PostgreSQL Versions Used By NetWorker

The NetWorker Management Console (NMC) and NetWorker Web User Interface (NWUI) servers include a Postgres database. The version of Postgres used by each component differs depending on the NetWorker version installed. NetWorker typically upgrades the Postgres versions in major and cumulative hotfix releases. 

NetWorker Management Console (NMC) PostgreSQL Versions:

• NetWorker version 19.10.0.0 uses 11.21
• NetWorker versions 19.10.0.4, 19.11.0.0 use 12.18
• NetWorker versions 19.10.0.7, 19.11.0.3, 19.12.0.0 use 16.4
• NetWorker versions 19.11.0.5, 19.12.0.1 use 16.6
• NetWorker versions 19.11.0.6, 19.12.0.2, 19.13.0.0 use 16.8
• NetWorker versions 19.12.0.3, 19.13.0.2 uses  16.9
• NetWorker versions 19.13.0.3, 19.14.0.0 use 16.10
• NetWorker version 19.14.0.1 is expected to us 16.14 (or newer)

NetWorker Web User Interface (NWUI) PostgreSQL Versions:

• NetWorker version 19.10.0.0 uses 12.16
• NetWorker versions 19.10.0.4, 19.11.0.0 use 12.18
• NetWorker version 19.13.0.0 uses 16.6
• NetWorker versions 19.13.0.3, 19.14.0.0 use 16.10
• NetWorker version 19.14.0.1 is expected to use 16.14 (or newer)

How to Verify PostgreSQL Version In Use:

Linux:

• NetWorker Management Console (NMC) Server: From an elevated prompt on the NMC server, run: systemctl status gst

The output shows the path of the nmcdb, which includes the PostgreSQL version:

[root@nsr ~]# systemctl status gst

Alternatively, if the NMC gst service is not running, look at the postgres_latest symbolic link used in the /opt/lgtonmc folder.

To see what minor PostgreSQL version is used, run the following command using the PostgreSQL path returned from the above command: strings /opt/nwui/monitoring/postgres/##/bin/postgres | grep "(PostgreSQL)"

[root@nsr ~]# strings /opt/nwui/monitoring/postgres/16/bin/postgres | grep "(PostgreSQL)"
postgres (PostgreSQL) 16.10
[root@nsr ~]#

Windows:

• NetWorker Management Console (NMC):

1. 1. Open Windows Task Manager on the NMC server.
   2. Go to the Details tab.
   3. Ensure that the Command line column is enabled.
   4. Look for the postgres.exe that is associated with the NetWorker Management Console server's nmcdb installation path. The Command line path shows the PostgreSQL version:

Alternatively, from a PowerShell prompt use the following command to check the postgres_latest symbolic link in your NMC install path: (Get-Item "C:\Program Files\EMC NetWorker\Management\GST\postgres_latest").Target

• NetWorker Web User Interface (NWUI):

1. 1. Open Windows Task Manager on the NWUI server.
   2. Go to the Details tab.
   3. Ensure that the Command line column is enabled.
   4. Look for the postgres.exe that is associated with the NetWorker Web UI server's nwuidb installation path. The Command line path shows the major PostgreSQL version

1. 5. To get the minor Postgres version, open Windows File explorer and go to the postgres.exe path shown in the Command line column.
   6. Right click postgres.exe and click Properties.
   7. The Details tab shows the full Postgres version:
