Because it is critical to let the user know as well *why* an error happened. Imagine that this feature is used with multiple nodes, all primaries. If a DB admin busted the credentials in one of them then all the load would be redirected on the other nodes, without knowing what is actually causing the error. Then the node where the credentials have been changed would just run idle, and the application would be unaware of that. -- Michael -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
