Thanks to Ward for the patience going through the new deployment instructions, and for spotting the pg_hba.conf typo.

In the issue #395 & PR #396, one workflow would not render after migrating the data from MongoDB to PostgreSQL.

After troubleshooting it, I realized it was due to a change in recent versions of Thymeleaf (template used in SpringBoot). It disallows static methods accessed in the template. I've rebased this branch, and added a change to send the result of the static method from the controller, already processed, to the template.

Tested on the workflow that was not rendering and it fixed the problem 🎉 🥳 N.B. this does not block the MongoDB migration, since once the template is fixed, the workflow graph will be rendered just fine.
