Since HAVE_UNIX_SOCKETS is now defined unconditionally, remove the macro and drop a small amount of dead code. The last known systems not to have them (as far as I know at least) were QNX, which we de-supported years ago, and Windows, which now has them. If a new OS ever shows up with the POSIX sockets API but without working AF_UNIX, it'll presumably still be able to compile the code, and fail at runtime with an unsupported address family error. We might want to consider adding a HINT that you should turn off the option to use it if your network stack doesn't support it at that point, but it doesn't seem worth making the relevant code conditional at compile time. Also adjust a couple of places in the docs and comments that referred to builds without Unix-domain sockets, since there aren't any. Windows still gets a special mention in those places, though, because we don't try to use them by default there yet.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
