Not sure if I got it: so EXPLAIN will return tuples to libpq client. But how do we store these returned tuples (RelOptInfo, Path etc) so we can throw queries against them later? Something like this: INSERT INTO my_space SELECT (EXPLAIN SELECT ...); -- won't get parsed Regards, Qingqing -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
