Incredible bug

[GreenplumDB]

Hello, I have been using the piplinedb plugin for a while, but I recently encountered a very strange phenomenon. When I implemented a process, I needed to repeatedly delete the SQL that created the pipelinedb. I found that the foregin table could not be read from kafka or Insert data, and even if you delete the plug-in and create it again, it will not get better. Only by recreating a new postgresql instance can it be restored. Looking forward to your answer, thank you.
