COPY INTO FILE - Folder permission

Hi! We are running some "exports" using the COPY INTO FILE, the problem we are facing is that the file created by monetdb is Read Write ONLY by the user running the database.

-rw------- 1 root monet 9477 Sep 7 15:08 exp.csv

Is there any way so the created file has also RW permission to the group and NOT only the user.

In this case, we are using an NFS share so we are not able to use setfacl.

Does anybody has an idea how to solve this ?

Thanks a lot in advance! Rgds Ariel
