Tom Lane 5b570d771b Un-break parallel pg_upgrade. 
Commit b3f840120 changed pg_upgrade so that it'd actually drop and
re-create the template1 and postgres databases in the new cluster.
That works fine, serially.  With the -j option it's not so fine, because
other per-database jobs might be launched while the template1 database is
dropped.  Since they attempt to connect there to start up, kaboom.

This is the cause of the intermittent failures buildfarm member jacana
has been showing for the last month; evidently it is the only BF member
configured to run the pg_upgrade test with parallelism enabled.

Fix by processing template1 separately before we get into the parallel
sub-job launch loop.  (We could alternatively have made the postgres DB
be the special case, but it seems likely that template1 will contain
less stuff and so we lose less parallelism with this choice.)

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/.
