I'm afraid I will almost certainly be unable to use RETURN QUERY. I have
just broken this down to the posted code to make it easier to understand.

In my real world code a loop will need to iterate over features of a postgis
geometry returning a couple of rows containing a string and a calculated
geometry as a result.
