Yes, that's what Noah and I talked about doing. Or possibly even making the map into a hash table in dynamic shared memory, so that new combo CIDs could be allocated by any backend in the parallel group. But that seems hard, so for starters I think we'll only parallelize read-only operations and just hand over a copy of the map. -- 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
