The number of hits could be different. However, it seems like any sequential scan, parallel or not, should have a number of accesses (hit + read) equal to the size of the relation. Not sure if that's what is happening here. -- 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
