I'm curious about the development Calendar Server's apparent need for PostgreSQL, but that (py)xattr is still called for. Rather than store .ics files directly in the filestore, will version 3.* use a relational database to store the equivalent data? (My apologies if I've missed a developers' document either in the checked-out development or on the website, but I have looked. I need to read the source, I know!) A calendar service which was (eventually!) used in an academic environment such as mine would have to have its users' calendar data backed up. Normally, we use a NetApp filestore for holding user files, via an NFS proxy. I shall look to see if extended attributes can be so supported, but if the aim is to store data with PostgreSQL, that might be an easier route. John A. Murdie
