I don't see this behaviour under 8.0.0, and it's presumably fixed:

Hi all!
Is there a way of echo'ing a string(like "raise notice 'this is id%', id")

It is very hard to help without you providing the schema for the tables/views

You haven't provided any information on how your tables/views look like and
