No PostgreSQL in Resolve Installer?

Hello Forum,

I am currently trying to install Resolve 18.1.1 on a new PC running Windows 11. The installer only shows Fairlight Audio Accelerator Utility and Resolve 18.1.1. No ProstgreSQL.
After installation I tried to import my DB backup and got the following error:

Failed to restore database: Failed to create project
library: project library test already exists.

The error persists no matter what name I use.
After that I tried to create a new library and got the following error:

could not connect to server: Connection refused
(0x0000274D/10061) Is the server running
on host "127.0.0.1" and accepting TCP/IP
connections on port 5432? QPSQL: Unable to connect

Then I uninstalled Resolve and tried it with versions 18.0 and 18.1 (the DB backup was created with version 18.1 and works on the old PC).

I do not have a PostgreSQL folder under C:\Program Files. It just doesn't install and the Resolve installer doesn't show it.

What I also noticed is that the Resolve installer says "Windows 10 (x64)" even though I'm on Windows 11.
Is Resolve compatible with Windows 11 at all? In the release notes I only find this:
"Minimum system requirements for Windows:
Windows 10 Creators Update."

Did anyone have the same problem?

It looks like you might need to install the Project Server to have PostgreSql installed.

Thank you very much, that was it!
My mistake, I must have read over that. In my old installation PostgreSQL was carried over from version 17 and therefore I didn't notice.
