One item should say something like: Improve hash join performance. The Teodor/Tom thing should say something like: Improve the performance of various in-memory hash tables.

I assume users would view those as separate things. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
