To take a step back, what prompted this whole discussion is the patch that I wrote that shifts down, replacing calls to tuplesort_heap_siftup() and tuplesort_heap_insert with one new call to a function I've called tuplesort_heap_root_displace() (today, Claudio reports that it makes some of his test queries go 25% faster). This new function shifts down. It's not clear what I'm supposed to say about that, given the current understanding. So, in a sense, it's blocking on this. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
