What is the status node injecting into the postgres node ? Why would you need the status node ?
The error describes the problem: payload must be an array of queries.
Can you clarify what problem you are seeing? Is it that the node does not show a status or that you are not getting any results. If the latter (or both) then
Which postresql node are you using (probably node-red-contrib-something) there appear to be a good handful of possible nodes it could be.
The original error message you posted said that the payload had to be an array of queries. Do you believe that error is incorrect? If the error is valid have you fixed that and what error do you get now?
Start node-red in a terminal and copy/paste the startup log here (it is the log with the Welcome to node-red message that we want).
