VIOM installations include a bundled Postgres database. To check the version that you have installed, please run the below command on the VIOM Management Server:
/opt/VRTSsfmcs/pgsql/bin/postgres -V
Example:
# /opt/VRTSsfmcs/pgsql/bin/postgres -V
postgres (PostgreSQL) 10.11
Sometimes the Postgres version will be upgraded with different versions of VIOM or VIOM patches. You will need to run the command above to determine the version that is running for your installation.
