Tom Lane d6eb5a0c25 Make psql's \password default to CURRENT_USER, not PQuser(conn). The documentation says plainly that \password acts on "the current user" by default. What it actually acted on, or tried to, was the username used to log into the current session. This is not the same thing if one has since done SET ROLE or SET SESSION AUTHENTICATION. Aside from the possible surprise factor, it's quite likely that the current role doesn't have permissions to set the password of the original role. To fix, use "SELECT CURRENT_USER" to get the role name to act on. (This syntax works with servers at least back to 7.0.) Also, in hopes of reducing confusion, include the role name that will be acted on in the password prompt. The discrepancy from the documentation makes this a bug, so back-patch to all supported branches. Patch by me; thanks to Nathan Bossart for review.

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/.
