Michael Paquier f483b20905 worker_spi: Fix another stability issue with BGWORKER_BYPASS_ALLOWCONN
worker_spi_launch() may report that a worker stopped when it fails to
connect on a database that does not allow connections if the worker
exits before the SQL function checks for the current status of the
worker.  The test is switched to use Cluster::psql instead of
safe_psql() so as it does not fail hard when this query errors.  While
on it, this removes a query that looks at pg_stat_activity to simplify
the test, as a check on the contents of the server logs achieves the
same when the worker cannot connect to the database without
datallowconn.

Per buildfarm members kestrel, mamba and serinus.  Bonus thanks to Tom
Lane for providing the logs of the failure from mamba that the buildfarm
was not able to show up.  Note that I have reproduced the failure with a
hardcoded stop point.

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
