Why?

Should it also be functional without sockets?

How about without a file system?

Without an OS?


PostgreSQL is an application running on an OS, and expects to be able to
use the basic services of that OS. Those services include local DNS
resolution of local host names. Every OS since Windows 3.1.1, Mac OS 7,
and early BSD UNIXes has provided local DNS resolution and loopback
sockets. Why should PostgreSQL accomodate the lack of them? If it
should, where does it stop accomodating broken and cut-down OSes?

If you want an embedded database for an extremely cut down OS,
PostgreSQL isn't particularly suitable for a lot of reasons. For any
other use case there's no reason to expect local DNS resolution to be
broken.
