[ADMIN] PostgreSQL and ZFS

[Thomas Bräutigam]

Hello,
 
I am working with a PostgreSQL Database and I want to change the Filesystem to 
ZFS.
 
Does someone have experience with PostgreSQL and its Performance with ZFS? Are 
the current write options for PostgreSQL suitable for ZFS?
 
Do I need to finetune Postgres with the settings for ZFS?
Like finetuning of...
- fsync
- wal_sync_method
 
Thanks if someone can help me on this.
 
Cheers Thomas
