Cause
Client authentication is controlled by a configuration file, which traditionally is named pg_hba.conf and is stored in the database cluster's data directory. For more information on postgres configuration file details:
http://www.postgresql.org/docs/9.2/static/auth-pg-hba-conf.html
Resolution
Add the IP address of the Confluence server to the pg_hba.conf and make sure that the method is not set to reject. You need to modify the xxx.xxx.xxx.xxx and put the IP address to allow connections.

# TYPE DATABASE USER CIDR-ADDRESS METHOD
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all xxx.xxx.xxx.xxx md5
# IPv6 local connections:
host all all ::1/128 md5Another example, 192.168.132.17/24 where 24 is the mask which would be 255.255.255.0. If it was 255.255.0.0 then the number would be 16. For more information consult the pg_hba.conf documentation page.
