Checking for duplicates in all cases would be wasteful, since often we are joining to the PK of a smaller table. If duplicates are possible at all for a join, then it would make sense to build the hash table more carefully to remove dupes. I think we should treat that as a separate issue. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
