You can't manually update to PostgreSQL 9.5.
Well, you can, but all your existing Resolve PostgreSQL databases will be gone.
Too late for you, but in case others are looking, you need to use the PostgreSQL update tools that are in the Resolve installers from 12.5.3 and up. And you need to use them BEFORE updating from El Cap to Sierra or High Sierra.
From the ReadMe notes in the 14.2 Mac installer:
Upgrading your PostgreSQL database server on Mac
Until DaVinci Resolve 12.5.2, the Mac installer used to ship with PostgreSQL version 8.4.2. Starting from macOS Sierra 10.12, PostgreSQL version 8.4 is no longer supported. If you intend to upgrade to the latest OS, you will need to upgrade your PostgreSQL database server to version 9.5.4 prior to upgrading macOS. Once your PostgreSQL installation has been upgraded and your data has been ported, you can then proceed with your macOS upgrade.
We have provided apps to simplify upgrading your PostgreSQL version on your Mac. The apps along with instructions can be found in the /Library/Application Support/Blackmagic Design/DaVinci Resolve/Upgrade PostgreSQL folder.
Starting from DaVinci Resolve 12.5.3, new installations will include PostgreSQL version 9.5.4.
