Which postgresql plist is the correct one?

Question

I am having trouble getting my wiki to work ("unable to read wiki configuration file" message). In my digging into this problem I am looking at a couple different plist files. I have updated this server lion to mountain lion and I'm not sure if one of these is left over from an earlier Server install.
I think this is the correct plist:
Server/PostgreSQL/Config/
[kirkw@truffula]Config$ more org.postgresql.postgres.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>ProgramArguments</key>
        <array>
                <string>-D</string>
                <string>/Library/Server/PostgreSQL/Data</string>
                <string>-c</string>
                <string>listen_addresses=127.0.0.1,::1</string>
                <string>-c</string>
                <string>log_connections=on</string>
                <string>-c</string>
                <string>log_directory=/Library/Logs/PostgreSQL</string>
                <string>-c</string>
                <string>log_filename=PostgreSQL.log</string>
                <string>-c</string>
                <string>log_line_prefix=%t </string>
                <string>-c</string>
                <string>log_lock_waits=on</string>
                <string>-c</string>
                <string>log_statement=ddl</string>
                <string>-c</string>
                <string>logging_collector=on</string>
                <string>-c</string>
                <string>unix_socket_directory=/private/var/pgsql_socket</string>
                <string>-c</string>
                <string>unix_socket_group=_postgres</string>
                <string>-c</string>
                <string>unix_socket_permissions=0770</string>
        </array>
</dict>
</plist>
However, there is also this plist in:
/Library/Preferences/
[kirkw@truffula]Preferences$ more org.postgresql.postgres.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>ProgramArguments</key>
        <array>
                <string>-D</string>
                <string>/Library/Server/PostgreSQL/Data</string>
                <string>-c</string>
                <string>unix_socket_directory=/var/pgsql_socket</string>
                <string>-c</string>
                <string>logging_collector=on</string>
                <string>-c</string>
                <string>log_connections=on</string>
                <string>-c</string>
                <string>log_lock_waits=on</string>
                <string>-c</string>
                <string>log_statement=ddl</string>
                <string>-c</string>
                <string>log_line_prefix=%t </string>
                <string>-c</string>
                <string>listen_addresses=</string>
                <string>-c</string>
                <string>log_directory=/Library/Logs/PostgreSQL</string>
                <string>-c</string>
                <string>log_filename=PostgreSQL.log</string>
                <string>-c</string>
                <string>unix_socket_group=_postgres</string>
                <string>-c</string>
                <string>unix_socket_permissions=0770</string>
        </array>
</dict>
</plist>
Culd these files be in conflict? Should I get rid of the plist in /Library/Preferences/?

They say you should get a email with the serial number and download instructions after purchase.
Your email should specify Mac and the download would be a .dmg file.
We are basically a user group and have no connection with this company, you have to contact them.
