Tom Lane c6eac71a88 Fix psql's \connect command some more. Jasen Betts reported yet another unintended side effect of commit `85c54287a`: reconnecting with "\c service=whatever" did not have the expected results. The reason is that starting from the output of PQconndefaults() effectively allows environment variables (such as PGPORT) to override entries in the service file, whereas the normal priority is the other way around. Not using PQconndefaults at all would require yet a third main code path in do_connect's parameter setup, so I don't really want to fix it that way. But we can have the logic effectively ignore all the default values for just a couple more lines of code. This patch doesn't change the behavior for "\c -reuse-previous=on service=whatever". That remains significantly different from before `85c54287a`, because many more parameters will be re-used, and thus not be possible for service entries to replace. But I think this is (mostly?) intentional. In any case, since libpq does not report where it got parameter values from, it's hard to do differently. Per bug #16936 from Jasen Betts. As with the previous patches, back-patch to all supported branches. (9.5 is unfortunately now out of support, so this won't get fixed there.)

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/.
