Heeeeeeeeeeeeeeeeeeelp!!!!

When startng my Linux server Postgresql fails to start. Says something about the Postmaster not finding data directory.

When I login as postgres and type,

postmaster status

I get this message,

/usr/bin/postmaster does not know where to find the database system data. You m
ust specify the directory that contains the database system either by specifying
the -D invocation option or by setting the PGDATA environment variable.

No data directory -- can't proceed.

Any ideas?

Gaaaah! I get the same errors..

Yes, it's a pain in the butt.

The main problem sees to be that in order to access the data files you need to be root and in order to run postmaster and postgresql you can't be root!!!

If you su to postgres you get the error than postmaster is already running (even though it's not!)

I'm lost.

It's doesn't seem to make sense in the documentation from the postgresql site either. Judging by the number of people having these setup problems (just on this site), some clarification is badly needed.

I run RedHat 7.0 and I have had no problems doing su postgres and working with the database. You might want to check and make sure that you have initialized a database.

Try psql -l

It will list all of the tables in the database. It sounds like you may need to create a few tables to get started.

Also, there is a new book out called PostgresSQL. I picked it up about 3 weeks ago and it has explained a lot. The book assumes no prior knowlede of SQL or databases. It might be boring for someone with years of experience, but for someone like me who is just starting it is perfect.
