Michael Paquier dc57366c58 Fix check for PGHOST[ADDR] in pg_upgrade with Windows and temporary paths
The checks currently done at the startup of pg_upgrade on PGHOST and
PGHOSTADDR to avoid any attempts to access to an external cluster fail
setting those parameters to Windows paths or even temporary paths
prefixed by an '@', as it only considers as a valid path strings
beginning with a slash.

As mentioned by Andres, is_unixsock_path() is designed to detect such
cases, so, like any other code paths dealing with the same problem (psql
and libpq), use it rather than assuming that all valid paths are
prefixed with just a slash.

This issue has been found while testing the TAP tests of pg_upgrade
through the CI on Windows.  This is a bug, but nobody has complained
about it since pg_upgrade exists so no backpatch is done, at least for
now.

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
