Michael Paquier 96bef4374e Fix inconsistent error handling for GSS encryption in PQconnectPoll() 
The error cases for TLS and GSS encryption were inconsistent.  After TLS
fails, the connection is marked as dead and follow-up calls of
PQconnectPoll() would return immediately, but GSS encryption was not
doing that, so the connection would still have been allowed to enter the
GSS handling code.  This was handled incorrectly when gssencmode was set
to "require".  "prefer" was working correctly, and this could not happen
under "disable" as GSS encryption would not be attempted.

This commit makes the error handling of GSS encryption on par with TLS
portion, fixing the case of gssencmode=require.

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/.
