A tablespace/bufferpool match is defined. Then tables and indexes are assigned to the tablespace (and implicitly, the bufferpool). As a result, one can effectively pin data in memory.

I assumed that the point was to get to a DB2-like structure at some point. Yes? We already have tablespaces, and our data already is accessed through the buffer pool. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
