I am struggling with the following problem.
I have read the following guide: [Getting new files to inherit group permissions on Linux][1]
Yet, this has not helped me.

(pgcluu is a postgresql cluster monitoring program)

I am using `Debian server`

I have a folder `/var/www/pgcluu`

Inside that folder i have
`stats` `reports` folders.
I have changed `stats` folder permission and ownership over to postgres.
`chmod -R postgres:postgres /var/www/pgcluu` (so the full folder is owner by postgres)

pgCluu on the other hand is collecting data and is generating files inside `stats` folder.
Looking something like.
`/var/www/pgcluu/stat/2018/04/04/09` 
basically `/year/month/day/hour/`
Inside the `hour` folder i have files like 

 
 -rw-r-----+ 1 postgres postgres 44 Apr 4 10:20 pg_stat_connections.csv
 -rw-r-----+ 1 postgres postgres 940 Apr 4 10:20 pg_stat_database_conflicts.csv
 -rw-r-----+ 1 postgres postgres 2479 Apr 4 10:20 pg_stat_database.csv
 -rw-r-----+ 1 postgres postgres 1 Apr 4 10:20 pg_stat_replication.csv
 -rw-r-----+ 1 postgres postgres 0 Apr 4 10:20 pg_stat_statements.csv
 -rw-r-----+ 1 postgres postgres 88 Apr 4 10:20 postgresql.auto.conf
 -rw-r-----+ 1 postgres postgres 21425 Apr 4 10:20 postgresql.conf
 -rw-r-----+ 1 postgres postgres 70009 Apr 4 10:20 sysinfo.txt

This is just an example, there are alot of more files.

The files are generated by `pgcluu_collectd` every minute (u can change it)
But they need to be rewritten, therefor it needs to have `rw- rw- ---` permissions to do it. (Owner and group must have read and write on the files)
Each time i change it myself, pgcluu_collectd makes the files with `rw- r-- ---` permissions again.

Therefor, is there a away that the files would inherit permissions from the folder `/var/www/pgcluu/stats`

 root@p12: getfacl /var/www/pgcluu/stats/

 # file: var/www/pgcluu/stats/
 # owner: postgres
 # group: postgres
 # flags: -s-
 user::rwx
 group::rwx
 other::---
 default:user::rwx
 default:group::r-x
 default:group:postgres:r-x
 default:mask::r-x
 default:other::---

and on the file

 root@p12:getfacl /var/www/pgcluu/stats/2018/04/04/10/pg_hba.conf 
 # file: var/www/pgcluu/stats/2018/04/04/10/pg_hba.conf
 # owner: postgres
 # group: postgres
 user::rw-
 group::r-x			#effective:r--
 group:postgres:r-x		#effective:r--
 mask::r--
 other::---
