Summary of RETURN SETOF variants

We learned that you can return table-like data sets from a function using one of the following:

RETURNS ...	RECORD structure	INSIDE function
SETOF <type>	From type definition	DECLARE row variable of ROW or RECORD type ASSIGN to row variable RETURN NEXT var;
SETOF <table/view>	Same as table or view structure
SETOF RECORD	Dynamic, using AS (name type, …) at call site
SETOF RECORD	Using OUT and INOUT function arguments. Assign to OUT variables. RETURN NEXT ;
TABLE (...)	Declared in-line in parentheses after TABLE keyword, converted to OUT variables for use in function. Assigned to OUT variables from the TABLE(...) part of the declaration. RETURN NEXT ;
