Your question about setting PGDATA was really about setting environmental variables in a shell; it is only incidental to PostgreSQL. There is an enormous amount of background knowledge assumed when you document an application, and this is necessary, or else every document would become a Windows-like spoon-feeder, which would spend so much time on basic stuff that it would never cover the real meat.

Yes. It is. Especially for fundamental, widespread technology like
PostgreSQL.
AT LEAST the community articles and additionally available documentation
should cater for mature people from many experience levels.
We can give guidance in newbie terminology for the basic concepts of
keeping their system operational long enough for them to get the hang of
it and go from there. i.e. a Kickstart guide.
Newbies have interesting ideas sometimes too. After all, they've spent
their time learning about something OTHER than Unix. :-)

You obviously have to assume the basics, like file management. An issue like the one I got stuck on, on the other hand, is not so basic (not covered in the thousands of pages of Unix documentation I consulted) and could have been explained with a single line example. In many ways it is a matter of mindset - when experienced people are writing it is difficult for them to visualise the roadblocks that will catch out those with less knowledge. More beginner friendly docs don't need to be much more verbose - it's about testing them and pinpointing the points of difficulty. The docs have room for many pages on how to do a SELECT, which is covered in detail in every SQL primer, so there is surely no reason why setup should not be covered a bit more clearly. Postgres is not so hard to use, but it is a bit of a pig to administer, and the docs are part of the problem. But I do understand that top quality docs require specific skills and resources which it is perhaps unreasonable to expect from an open source project. It will probably take a commercial effort from GreatBridge or a book to improve things. GreatBridge have made a start. I hope they continue to test and develop their docs, and don't regard the job as done... Geoff Caplan

Can you give us an example? ;-) But really: sure! Oracle, ferinstance, realizes that many people run Unix *because* they want to run Oracle in a stable server environment. People may be making the same decision about PostgreSQL. We shouldn't have to write this, though... if people could contribute the great 'basics of Unix you need to know to be a decent DBA' stuff that's already on the web, we'd have plenty. -- Joel Burton <jburton@scw.org> Director of Information Systems, Support Center of Washington
Joel- In all fairness, there aren't any good HTML-based Unix tutorials. I've looked for them. In particular, Sun is worthless here, curious since their Java tutorial is (IMO) really well done. I'm hoping PostgreSQL is MORE stable than Oracle in our Solaris environment. The massive CPU/disk footprint of Oracle generates reliability errors in our databases which I hope can be avoided in a leaner package. This marvelous mailing list really gives me confidence.
