Tom Lane 4ea03f3f4e Improve stability of partition_prune regression test. This test already knew that, to get stable test output, it had to hide "loops" counts in EXPLAIN ANALYZE results. But that's not nearly enough: if we get a smaller number of workers than we planned for, then the "Workers Launched" number will change, and so will all the rows and loops counts up to the Gather node. This has resulted in repeated failures in the buildfarm, so adjust the test to filter out all these counts. (Really, we wouldn't bother with EXPLAIN ANALYZE at all here, except that currently the only way to verify that executor-time pruning has happened is to look for '(never executed)' annotations. Those are stable and needn't be filtered out.) Back-patch to v11 where the test was introduced. Discussion: https://postgr.es/m/11952.1569536725@sss.pgh.pa.us		6 years ago

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/.
