Tom Lane 9bb5eecce6 Avoid ECPG test failures in some GSS-capable environments.
Buildfarm member hamerkop has been reporting that two cases in
connect/test5.pgc show different error messages than the test expects,
because since commit ffa2e4670 libpq's connection failure messages
are exposing the fact that a GSS-encrypted connection was attempted
and failed.  That's pretty interesting information in itself, and
I certainly don't wish to shoot the messenger, but we need to do
something to stabilize the ECPG results.

For the second of these two failure cases, we can add the
gssencmode=disable option to prevent the discrepancy.  However,
that solution is problematic for the first failure, because the only
unique thing about that case is that it's testing a completely-omitted
connection target; there's noplace to add the option without defeating
the point of the test case.  After some thrashing around with
alternative fixes that turned out to have undesirable side-effects,
the most workable answer is just to give up and remove that test case.
Perhaps we can revert this later, if we figure out why the GSS code
is misbehaving in hamerkop's environment.

Thanks to Michael Paquier for exploration of alternatives.

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
