Hello! I don't know if there is the right place to ask my question. If not, please accept my apology. I'm totally new to Linux. And I have troubles using the PostgreSQL. I installed Redhat 6.0 and find there is postgresql already installed on my computer. Running the following command I get: //////////////////////////////////////////////////// $rpm -ql postgresql /etc/rc.d/init.d/postgresql /usr/bin/cleardbdir /usr/bin/createdb /usr/bin/createuser /usr/bin/destroydb /usr/bin/destroyuser /usr/bin/initdb /usr/bin/initlocation /usr/bin/pg_passwd /usr/bin/pg_version /usr/bin/postgres /usr/bin/postmaster /usr/doc/postgresql-6.4.2 ..... (All the /usr/doc entried are omitted here since they are too many) ...... /var/lib/pgsql /////////////////////////////////////////// I thought it's ok to start the postgresql server, so I run the following command but it complains: (the command was found in the "/etc/rc.d/init.d/postgresql" file) ////////////////////////////////////////////// $postmaster -i -D/var/lib/pgsql /usr/bin/postmaster does not find the database system. Expected to find it in the PGDATA directory "/var/lib/pgsql", but unable to open file with pathname "/var/lib/pgsql/base/template1/pg_class". No data directory -- can't proceed. //////////////////////////////////////////// I read the installation instruction of the PostgreSQL but it teaches you how to install from the beginning and expect you to use the file "postgresql-v6.4.tar.gz", which I haven't got on my computer. I also tried to run the following command: $initdb but it cannot work yet. Someone told me I should establish a data store for the PostgreSQL. What's that? How to? Do I need to download "postgresql-v6.4.tar.gz" to re-install the PostgreSQL? Or how can I solve my problem? What's in the earth wrong? What's indeed the PGDATA mean? Any suggestion or hints are appreciated greatly! With my best regard: Janet
