Given what you are doing, RETURN TABLE it will not work there for the
same reason it does not work in 9.5:

https://www.postgresql.org/docs/9.6/static/plpgsql-control-structures.html#PLPGSQL-STATEMENTS-RETURNING

"If you declared the function with output parameters, write just RETURN
NEXT with no expression. On each execution, the current values of the
output parameter variable(s) will be saved for eventual return as a row
of the result. Note that you must declare the function as returning
SETOF record when there are multiple output parameters, or SETOF
sometype when there is just one output parameter of type sometype, in
order to create a set-returning function with output parameters."
