Per:
https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.AuroraPostgreSQL.html
Aurora Postgres is not the community edition, you should probably take
this up with AWS support.
Sure will raise a ticket. I was trying to understand though , if it's possible in postgres to have these sudden "recovery errors" possible because of some long running DML/DDL killed unexpectedly using the "pg_terminate/pg_cancel" command? And if this error appears in community postgres and if it stays for a long time what we used to do?
