What versions include the database installation and setup for PostgreSQL? Looking to have it set up a database automatically
Component : AUTOMATION ENGINE One Installer
PostgreSQL was not a supported database until 12.2.x; so it will not be available in the 12.0 or 12.1 One Installer.
As a note, the one installer should not be used for production systems as it's not "production ready" even as of 12.3.x
