I tryed to reinstal missing nodes but they where removed from node library website.  
How the flow using these nodes where very simple, I removed it and re-started node-red; but still have missing node error message.  
I just would like to remove missing node error any help will be apprecited.

In node red click on the hamburger menu and select Configuration nodes, then click Unused. If there are any (there may be a postgres config node) then double click each one to open it and click delete in the top left. When all deleted click Deploy.
