Good point. But data files are a function of tables and indexes, right? Having them in different schemas or different clusters isn't going to change that. I guess there are system tables but those are relatively trivial - I think? > b) its own postgresql processes (many of them) running in memory I believe this is entirely a function of client connections. > c) its own shared_buffers in memory. Given that each application will be independent, I don't see a different between clusters and schemas here either. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
