Hi.Which operations invoke the sorting algorithms implemented in the sorting module (tuplesort.c) ? Of course, one of those operations invoking sorting is the ORDER BY clause and the DISTINCT too.
Moreover, the Merge Join should be implemented invoking sorting. Is there any other operation invoking sorting? Thanks. Regards. Fava -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
