I tried to run postmaster after login in as postgre user. However, it mentioned that the data path was not found and asked me to use the -D option. When I used the -D option and specified the data path to be /usr/lib/pqsql/data, it mentioned that it could not locate the certain program.<br><br>For your information, I installed the POSTGRESQL package when I installed my Linux server.<br><br>Thanks.
