There aren't any, just a fair number of people who know how to do it and=20 some scattered bits of lore on the subject. The quickest way to get some= =20 sort of estimate that is actually useful is to create a small prototype of= =20 some tables you expect will be the larger ones for the application, load=20 some data into them, measure how big they are, and then extrapolate from=20 there. I'm dumping links and notes on the subject of measurements like=20 that http://wiki.postgresql.org/wiki/Disk_Usage that should get you=20 started with such a simulation. -- * Greg Smith gsmith@gregsmith.com http://www.gregsmith.com Baltimore, MD=
