you keep getting the same answer because as you described your problem
it does *exactly* what you want to do. so, either you are not
describing the problem well or you are not understanding us:
postgres=# select * from each('a=>1,b=>2');
key | value
-----+-------
a | 1
b | 2
(2 rows)
can be dropped directly into plgsql
for record_variable in select * from each('a=>1,b=>2')
loop
<do stuff>
end loop;
etc. What's the issue?
