Hello all,

I am new to postgreSQL. I have installed postgreSQL 7.1.3-2 on Linux 7.2.
If I login as root (administrator) and change user as postgres I can create
database on /usr/local/pgsql/data which I created and changed its owner as
postgres.

root# mkdir usr/local/pgsql/data
root# chown postgres /usr/local/pgsql/data
root# su postgres
bash-2.3# initdb -D /usr/local/pgsql/data
bash-2.3# postmaster -D /usr/local/pgsql/data > logfile 2 >&1 &
bash-2.3# createdb testdb
bash-2.3# psql testdb

However, when I login as a normal linux user I cannot create database. So
it is a user management problem.

zf2linux# createdb mydb
FATAL 1: user 'zf2linux' does not exist

I have tried to create a user of zf2linux in postgreSQL but the error still
occurs.
If I try to change to postgres from zf1linux it asks for password.

zf2linux# su postgres
password: ******
incorrect password.

My pg_hba.conf is left as the default format:

local         all                         trust
host         all     127.0.0.1     255.255.255.255     trust

I must miss something before I allow other users to access the postgreSQL
server and account. Could you please help me with the problem?

Thanks for your attention and will sum.

Hi Zhiqiang,

You might take a look at the following link:

http://www.tek-tips.com/viewthread.cfm?SQID=449717&SPID=699&page=1

After you have postgres user properly setup, you can use pgaccess to
configure other users.

Be careful with your pg_hba.conf entries (read the comments in the file itself, they are lengthy but useful). What you configured (below) will allow anyone to connect to your database from any machine without validation, as long as their IP address has the first two blocks equal to your machine. Are you sure that's what you want?

Thank Leland and Andrews for your help.

I successfully use pgaccess to add users and now can start postgresql as a
normal user.

However, it seems pgaccess requires TCP/IP port connection so I have to
include
host          all    IP_address_of_pc     255.255.0.0        trust

in the pg_hba.conf.

Thanks, Andrew for your suggestion. I should change 255.255.0.0 to 255.255.255.255 to allow users of the PC to access the database.
