Support for collecting crash dumps on Windows

Browse Source 
Add support for collecting "minidump" style crash dumps on
Windows, by setting up an exception handling filter. Crash
dumps will be generated in PGDATA/crashdumps if the directory
is created (the existance of the directory is used as on/off
switch for the generation of the dumps).

<title>Collecting crash dumps on Windows</title>
<para>
If PostgreSQL on Windows crashes, it has the ability to generate
<productname>minidumps</> that can be used to track down the cause
for the crash, similar to core dumps on Unix. These dumps can be
read using the <productname>Windows Debugger Tools</> or using
<productname>Visual Studio</>. To enable the generation of dumps
on Windows, create a subdirectory named <filename>crashdumps</filename>
inside the cluster data directory. The dumps will then be written
into this directory with a unique name based on the identifier of
the crashing process and the current time of the crash.
