Heikki Linnakangas 344a113079 Don't use SCRAM-specific "e=invalid-proof" on invalid password. 
Instead, send the same FATAL message as with other password-based
authentication mechanisms. This gives a more user-friendly message:

psql: FATAL:  password authentication failed for user "test"

instead of:

psql: error received from server in SASL exchange: invalid-proof

Even before this patch, the server sent that FATAL message, after the
SCRAM-specific "e=invalid-proof" message. But libpq would stop at the
SCRAM error message, and not process the ErrorResponse that would come
after that. We could've taught libpq to check for an ErrorResponse after
failed authentication, but it's simpler to modify the server to send only
the ErrorResponse. The SCRAM specification allows for aborting the
authentication at any point, using an application-defined error mechanism,
like PostgreSQL's ErrorResponse. Using the e=invalid-proof message is
optional.

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:

	http://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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
