It can be a good idea, but surely with different syntax. Maybe this
statement can be enhanced to use record variable as target, and then the
usual syntax for composite value is

GET STACKED DIAGNOSTICS r := RETURNED_SQLSTATE, MESSAGE_TEXT,
PG_EXCEPTION_DETAIL, ...

I am not sure if this mailing list is good for proposing some new features
