PostgreSQL 9.1.4 will not install service scripts

Same setup as before, but with a different install command.

PostgreSQL refuses to install its service scripts into /etc/init.d/; in fact, I can’t find them anywhere (find / -regex ".*postgres.*")

command     => '/bin/mount -o remount exec /tmp                ;
                /bin/mkdir -m 0755 -p /opt/PostgreSQL/9.1      ;
                /tmp/setup/postgres-9.1.4.run                  
                  --mode unattended                            
                  --superaccount postgres                      
                  --superpassword sUP34_se<uR3^P4sSw0rd        
                  --datadir /opt/PostgreSQL/9.1/data           ;
                /usr/sbin/userdel postgres                     ; # for some reason, it does give itself (postgres)
                                                                 # permissions to its own files, which causes problems with initdb
                /bin/chmod 755 /opt/PostgreSQL/9.1 -R          ; # so I nuke them all back to o=rwx,ug=rx
                /tmp/setup/postgres-9.1.4.run                  
                  --mode unattended                            
                  --superaccount postgres                      
                  --superpassword sUP34_se<uR3^P4sSw0rd        
                  --datadir /opt/PostgreSQL/9.1/data           ;
                /bin/mount -o remount /tmp                     ;
                /bin/touch /tmp/mysetup/postgres_installed     ; ',

Is there any way I can get these files into /etc/init.d? Why won’t the installer place them here in the first place?

Unfortunately, it is unlikely that I can use a different version of PostgreSQL – 9.1.4 is the most recent version that has been ‘approved’.
