Pgpool - semanage config files - which filetype should I choose?
Solution founded: 


To repair this issue I must execute this comand:


  chcon -t httpd_user_rw_content_t pgpool.conf


and


  chcon -t httpd_user_rw_content_t pcp.conf




then pgpooladmin will show that those files are writable and will allow to click "Next" to install pgpoolAdmin.
Yay Cheers :D
