Operating system: CentOS release 6.2 (Final)
Description:

Hi,

I've installed the 9.3 beta 1 packages (via pgdg repo and yum) and when I
try to do an initdb it fails. /var/lib/pgsql/9.3/data has nothing in it when
I attempt the initdb :

#service postgresql-9.3 initdb
Initializing database:[FAILED]

# cat /var/lib/pgsql/9.3/pgstartup.log
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

fixing permissions on existing directory /var/lib/pgsql/9.3/data ... ok
creating directory /var/lib/pgsql/9.3/data/pg_xlog ... ok
initdb: could not create symbolic link "/var/lib/pgsql/9.3/data/pg_xlog":
File exists
initdb: removing contents of data directory "/var/lib/pgsql/9.3/data"
initdb: removing transaction log directory
"/var/lib/pgsql/9.3/data/pg_xlog"
could not open directory "/var/lib/pgsql/9.3/data/pg_xlog": No such file or
directory
initdb: failed to remove transaction log directory

Brad.

btw - on the bug reporting form, the popup version does not have 9.3 Beta as
an option for version
