So you can dump a coherent sample database in one command, not 207. Every user of PostgreSQL wants a dev/test database. If the database is large it isn't practical to take a complete copy. Nor is it practical to hand-write a data sampling extraction program and if you do, its usually imperfect in many ways. Adding this feature gives a very fast capability to create sample databases, or incremental backups for many cases. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
