Getting started early this year, I've finally found a way around the issues

some testing.

Possibly, but if you're worried about that sort of attack you just don't

I generally support this, but I wonder if this could have strange effects if a
name resolves to more than one IP address or even an IPv4 and an IPv6

Do we have a known issues section somewhere? If not, I would suggest we
split the TODO list into two big sections, one is the PostgreSQL
improvement part, the other is the known issues part.
AFAICS there are some long lasting problems there simply because hackers
are not aware of or too trouble

Let me give you a sky-high view of this. Database reliability requires
that the disk drive be 100% reliable. If any part of the disk storage
fails (I/O write failure, NFS failure) we have to assume that the disk
storage is corrupt and the database needs to be restored from backup.

Yes - if you assume that EINTR only happens on NFS mounts.
My point is that independent of NFS, the error checking
that I have found in the code is not complete even for
non-NFS file systems.
The read() and write() LINUX man pages do NOT specify that EINTR
is an NFS-only error.

Absolutely not. autovacuum takes locks just like a backend and has to
