Description of problem:
root@mypc# service postgresql initdb
fails because of existing directory /var/lib/pgsql/data/pg_log
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum install postgresql
2. yum install postgresql-server
3. service postgresql initdb
Actual results: FAIL
Expected results: OK
Works fine after deleting the directory
[root@mypc ~]# rmdir /var/lib/pgsql/data/pg_log/
This would most certainly not happen given only the claimed "steps to reproduce". You must have had a previous postgres installation in there at some point. Was there really nothing in /var/lib/pgsql/data/ except the pg_log subdirectory? Can you recall just how you got to this state?
Closing for lack of response.
