Tomas Vondra a16b2b960f Fix TAP test for remove_temp_files_after_crash 
The test included in cd91de0d17 had two simple flaws.

Firstly, the number of rows was low and on some platforms (e.g. 32-bit)
the sort did not require on-disk sort, so on those machines it was not
testing the automatic removal.  The test was however failing, because
without any temporary files the base/pgsql_tmp directory was not even
created.  Fixed by increasing the rowcount to 5000, which should be high
engough on any platform.

Secondly, the test used a simple sleep to wait for the temporary file to
be created.  This is obviously problematic, because on slow machines (or
with valgrind, CLOBBER_CACHE_ALWAYS etc.) it may take a while to create
the temporary file.  But we also want the tests run reasonably fast.
Fixed by instead relying on a UNIQUE constraint, blocking the query that
created the temporary file.

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/.
