Answer

Hello, I have been checking various sources about this problem, usually it is a low resource problem.

I recommend you create a clone of your database in production, in this clone increase the instance size and launch the upgrate to test if you still have the same problem.

Hi,

The error shared seems lack some info. Have you noticed something similar to:

"ERROR:  could not access file"
"ERROR: cache lookup failed for database 1"
"FATAL: database "template1" does not exist"

I would recommend share a full picture of the log here. Otherwise, double check the major steps mentioned in https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_UpgradeDBInstance.PostgreSQL.html#USER_UpgradeDBInstance.PostgreSQL.MajorVersion

For example:

--> Any extensions need to be upgraded first?
--> Any extensions need to be dropped? (chkpass, tsearch2)
