Andres Freund 7fdbdf2049 pgstat: fix stats.spec instability on slow machines. 
On slow machines the modified test could end up switching the order in which
transactional stats are reported in one session and non-transactional stats in
another session. As stats handling of truncate is implemented as setting
live/dead rows 0, the order in which a truncate's stats changes are applied,
relative to normal stats updates, matters. The handling of stats for truncate
hasn't changed due to shared memory stats, this is longstanding behavior.

We might want to improve truncate's stats handling in the future, but for now
just change the order of forced flushed to make the test stable.

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/.
