No -- I mean you can use BEGIN/EXCEPTION/END blocks as you like, nesting
them or putting one after another.  Complementing this with RAISE
EXCEPTION you can cause savepoints to roll back at will.

I have seen this feature being asked for, and this work-around suggested so many times. If plpgql does it internally, why not provide a clean interface for this? Is there some road-block, or that nobody has ever tried it?

If there are no known limitations, I'd like to start work on it.
