Dear,
I am thinking to shift my software Axbo7.1 (see
http://axbo.co.in/ )
to postgresql from mysql.
I have Suse 10.2 operating system in my organization.I
install version 8.1.5-13 successfuly.
but when I start server as------------>
pg_ctl start -D /var/lib/pgsql/data
then error is----------------->
postmaster started.
Could not open directory "base" No such file or
directory.

If you can't help then give any of address from whom I
can get help.
