+[n8n](https://n8n.io/) is an extendable workflow automation tool.

+> When application is installed, a container will be launched with **root** privileges.
+> This is required in order to apply the correct permissions to the `postgres` directories.
+> Afterward, the `postgres` container will run as a **non**-root user (`999`).
+> On each upgrade, a container will be launched with **root** privileges in order to apply the correct
+> permissions to the `postgres` **backups** directory. Container that performs the backup will run as a **non**-root user (`999`) afterwards.
+> Keep in mind the permissions on the backup directory will be changed to `999:999` on **every** update.
+> But will only be changed once for the `postgres` data directories.
