  Mac suddenly not recognizing DeckLink HD Extreme 3D

  Posted by Alex Frankland on March 1, 2012 at 7:58 am

  Hi guys,

  I’m trying to get my new DaVinci Resolve setup started and encountered this error message numerous times, even after uninstalling Resolve and re-installing…

  “Failed to open database connection: could not connect to server:Connection refused. Is this server running on host “127.0.0.1 and accepting. TCP/IP connections on port 5432? QPSQL: Unable to connect”.

  Does anyone know how I can fix this? I am currently running OSX 10.7.3 and installed the new NVIDIA driver as advised from this post. https://forums.creativecow.net/readpost/277/14876
  And it all seems to work apart from Resolve that keeps closing once I attempt to adjust settings in the conform page. Database issue perhaps?

  Any help would be much appreciated.

  – Alex

  ps, I am new to DaVinci and still in the process of understanding how the entire system works.

  All good, I contacted BMD and they told me exactly what to type in Terminal. All seems to be ok now.
  Sorry about typing the wrong subject earlier.

  Alex.

  [Chris Borjis] “what did you type in the terminal to fix?”

  Hey Chris,

  Here were my exact instructions from BMD. After going through this procedure, everything worked fine.

  Failed to open database connection

  Symptom: Failed to open database connection: connection refused. Is the server running on 127.0.0.1 and accepting TCP/IP connections on port 5432? QPSQL:Unable to connect.”

  Cause: Unknown

  Solution: Manually unintsall the PostgreSQL and then reinstall the Resolve app again.

  Procedure:
  Manual Uninstallation:

  Open a terminal

  1) Stop the server

  sudo /sbin/SystemStarter stop postgresql-8.4

  2) Remove menu shortcuts:

  sudo rm -rf /Applications/PostgreSQL 8.4

  3) Remove the ini file

  sudo rm -rf /etc/postgres-reg.ini

  4) Removing Startup Items

  sudo rm -rf /Library/StartupItems/postgresql-8.4

  5) Remove the data and installed files

  sudo rm -rf /Library/PostgreSQL/8.4

  6) Delete the user postgres

  sudo dscl . delete /users/postgres

  7) Re-install Resolve

  Regards

  – Alex
