Accessing to those data have been talked about with respect to DDL
triggers too. You want to be able to know what exactly is being
executed, and against what objects.
And you want to be able to abuse this information from either a C-coded
server function or a PLpgSQL trigger. I guess the WIP JSON datatype
would help a lot even when working from within the server, as that does
not mean working in C.
