Installing PostgreSQL 13 on QNAP for Davinci Resolve

This guide aims to provide an updated overview on installing PostgreSQL 13 within a QNAP NAS for use as a database inside Davinci Resolve.

The previous guide(s) created by QNAP are somewhat irrelevant as Davinci Resolve, Container Station and QTS/QuTS have since undergone major upgrades.

These original guides are linked below for reference:
