Years ago (2010 iirc), I reported to the Postgres list, with a patch, that (one of) the reason Postgres “didn’t work on NFS” was because it couldn’t deal with short writes. I got told the usual “you’re holding it wrong” instead of an acknowledgement of PG not sticking to the spec.
I patched my own systems (wrap the calls in a loop as per standard practice) and then proceeded to run literally hundreds of thousands of PostgreSQL instances on NFS for many more years with no problems.
The patch was eventually integrated it seems but I never found out why because I lost interest in trying to work with the community after that experience.
