Encountering 'Unrecognized Node Type: 366' Error in Aurora PostgreSQL Serverless V2

Hello AWS Community,

I'm seeking advice regarding a persistent error we're facing with our Aurora PostgreSQL Serverless V2 setup running PostgreSQL 15.5. We are periodically receiving an error message: "unrecognized node type: 366". This error doesn't seem to correlate with specific operations or changes in our environment, making it particularly puzzling.

Here are some details about our setup:

Database Version: PostgreSQL 15.5 Configuration: Aurora Serverless V2 Error Encountered: "unrecognized node type: 366" The error message is vague and doesn't appear to be directly linked to any recent updates or schema changes we've implemented. Given the sporadic nature of the error, I'm concerned about the stability and reliability of our database operations.

I'm looking for insights on the following:

1. Has anyone in the community encountered this specific error or a similar issue?
2. What does "unrecognized node type: 366" indicate in an Aurora PostgreSQL context?
3. Are there any recommended steps for diagnosing or resolving this type of error in Aurora Serverless environments?
4. Any suggestions, guidance, or shared experiences with similar issues would be greatly appreciated as we navigate this challenge.

Thank you in advance for your help and insights!
