A valid PostgreSQL CMS connection could not be established.

every tme I run daz studio I get this error message A valid PostgreSQL CMS connection could not be established.  Several DAZ Studio features that require a valid PostgreSQL CMS connection, such as context aware content views and loading content installed using the Daz Connect service, will not be available.
Check any network, anti-virus, anti-malware, anti-ransomware, and/or firewall settings for potential conflicts.I have tried every thing I can thing of and even tried a couple of tricks I found on the web. But nothing seem to work.

Have you tried to make sure it is installed, or uninstall it then reinstall it?

I just had this problem and I believe it was actually some kind of authorization problem caused by a previous installation on a machine where I recently tried to install Daz again.

After installing through DIM the postgres connection worked fine, I would also get my products in smart content, but there was still that "Could not establish valid Postgres connection" error when starting Daz. To solve it I had to not just uninstall everything Daz related, but also manually delete %APPDATA%\DAZ 3D and everything else I could find, then also use regedit to search for "DAZ 3D" and delete all relevant keys there as well (one in particular had all kinds of Daz settings, like my login email I think).

After I've done that it worked again.

You can tell if you've really cleaned up your old installation if Daz asks you to participate in the DAZ Studio improvement program on first startup, and asks you to login etc. If it doesn't do that then you still have some stale login data that I believe can cause this error.

It may also have been permission issues on one of the files or folders you deleted, rather than a registry issue (and editing the Registry is a pretty high-risk action, certainly doing it broad-brush).
