Peter Eisentraut bf68b79e50 Refactor ps_status.c API
The init_ps_display() arguments were mostly lies by now, so to match
typical usage, just use one argument and let the caller assemble it
from multiple sources if necessary.  The only user of the additional
arguments is BackendInitialize(), which was already doing string
assembly on the caller side anyway.

Remove the second argument of set_ps_display() ("force") and just
handle that in init_ps_display() internally.

BackendInitialize() also used to set the initial status as
"authentication", but that was very far from where authentication
actually happened.  So now it's set to "initializing" and then
"authentication" just before the actual call to
ClientAuthentication().

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/.
