Use the following steps to initialize the databases of the Trifacta® platform.
NOTE: These steps assume that the Trifacta node is the host of these databases. Please modify the following steps if you are connecting to databases on other nodes.
- The initializing user must have write permissions to the directory from which the commands are executed.
- The initializing user must have sudo privileges.

- Make changes in the file as needed and save.
Apply customizations on upgrade
If you have customized database properties, you must apply the edits from the new sample file to the existing configuration file after you have upgrade the Trifacta platform.
If you are using all defaults, you can just overwrite the existing file with the new version's sample file.
Locate the sample Postgres configuration file:
- If you are upgrading and have customizations in your existing version, you must apply the edits in the above to the following file. Otherwise, overwrite the following file with the above one based on your operating system:
