Tom Lane 7606bbb3de Make stats regression test more robust in the face of parallel query. Commit `60690a6fe` attempted to fix the wait_for_stats() function in this test so that it would wait properly if the tenk2 scans were done in parallel workers instead of the main session (typically as a consequence of force_parallel_mode being turned on). However, we made it test for whether the main session's actions had been reported by looking for inserts on 'trunc_stats_test'. This is the Wrong Thing, because those aren't the last updates we expect the main session to do. As shown by recent failures on buildfarm member frogmouth, it's entirely likely that the trunc_stats_test updates will be reported in a separate message from later updates, which means there can be a window in which wait_for_stats() will exit but not all the updates we are expecting to see will have arrived. We should test for the last updates we're expecting, namely those on 'trunc_stats_test4'. Unfortunately, I doubt that this explains frogmouth's failures, because there's no reason to believe that it's running the tenk2 queries in parallel. Still, the test is wrong on its own terms, so fix and back-patch to 9.6 where parallel query came in.		2017-05-14 21:39:10 -04:00

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:

	http://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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
