Yes, this is the best I have come up with so far. I have a set
returning function which returns the key and the index number. The
implementation with a cursor looks like this:
SELECT * FROM cursor_pk('c1') c LEFT JOIN foo ON (c.pk = foo.pk) ORDER
BY c.idx;
An array function could return the same values. I need to do some
testing to see what the performance looks likes for each method.
Thanks for the suggestion.
