Per: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.AuroraPostgreSQL.html <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?
Since you have provided essentially zero information about your setup there is no real way to answer the above.
