I really do not see the point of PERFORM in the current implementation of PL/pgSQL. If we were to allow SELECT to run
whenit is not returning a value or selecting into a variable, it would be unambiguous, since the other two cases
require:

* Using RETURN (or RETURN QUERY)
* The INTO clause

I have come around to the position that I think Tom, Josh, and Merlin have all put forward, that PERFORM is
unnecessary.

Unless Jan chimes in with something the rest of us have missed, it’s starting to feel like a consensus to me, other
thanyour objections, of course. 

Best,
