This surprised me when I first started to use PG (after all those years with ORCL). There are some use cases where this limitation is a nuisance. For example, if you want to implement the famous retry loop (with exponential backoff) for an error that is provoked at commit time... well, you have to do it in client-side code. Could the limitation be lifted by making tractable internal implementation changes? Or is it rooted in profoundly deep features of the architecture—meaning that it could never be lifted?
