Hi all,
I am new to pgsql family.I had a problem with
installing postgres8.1 i was getting the following
error at the 4th step of installation the error is as
follows:

Data directory error:
The specified data directory is not empty

If you have an existing database with teh same
major version number,you do not need to initialise a
database cluster.
If you have an existing database with the same
major version you need to backup your old database and
create a new one.

why this warning actually arises.If I install by
unchecking the initialise database cluster then the
next three steps of installation procedure is not
shown.It goes directly installation and starts
installation after some time a fatal error arises
saying accont not matching....................
and rolls back.i have tried it with lots of
account names and lot of super user names.The steps i
was talking about are as per the given link.

Can any one give the solution to this
problem.Please suggest solution to overcome this
problem ASAP.

Thanks in advance,
Venu.

Why not just try the obvious and delete anything in
the target installation directory and retry?
Maybe you have some old version from earlier attempt
there? Alternatively you could install into another
location. Did you make sure you dont have another
postgres version installed and even actually running?

Hi Tino Wildenhain,
Sorry for irritating you with my problems.Every
time i run my installing it gives different problems
and rolls back.Once when i move with account name as
postgres it gives problem as "user account exists"
and rollsback.
If i try with different user it gives problem as
Internal Account look up failure:NO mapping between
account names and security Ids done

I am sure that no other Postgres exists in my
directory(c:\programfiles\).But while installing my
wampapache and wampmysqld are running.

Can u please give me how can i solve this
problem.Is there any possibility that UserAccounts are
stored other than the directory where we are
installing the directory.

How can we browse my postgres to be installed in a
different location by default it is installing in
c:\programfiles\

sorry if i trouble you with these questions but i
need it to be installed to get worked with maps using
PGIS.

Can u give me the solution ASAP.

Thanks and Regards,
Venu.
