Hmm. I'm not sure it wouldn't end up being *less* memory. Don't we end up caching 1 copy of it per backend, at least for the database to which that backend is connected? Accessing a shared copy would avoid that sort of thing. -- 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
