Thanks for advice. I'll try it!

Very interesting. For some reason I always thought that no one runs PostgreSQL on ZFS. If it's not a secret, what company uses PostgreSQL on FreeBSD like this?

Frankly I don't remember, it was more then half a year ago. LZ4 is a LZ77 family algorithm which means its dictionary is a "shifting window". I don't believe such kind of dictionar…

No, I didn't test it on ZFS. Sorry for asking, but is there any reason to run DBMS (which I would like to remind has a build-in compression) on ZFS which itself is a small DBMS? So…

Thank you for an interesting idea! I can't promise I will implement it myself any time soon, however. You know the saying - pull requests are welcome :)

I'm afraid Snappy will not help, at least a lot. PostgreSQL already has a build-in compression (PGLZ). I tested various different algorithms before this shared-dictionary-idea - lz…

Frankly I don't remember all details since I did this benchmark in February. IIRC its "ZSON + PGLZ" vs "JSONB + PGLZ". Please note that everything depends very much on your data. P…
