Disable <xref linkend="guc-update-process-title"> by default on
Windows (Takayuki Tsunakawa)
</para>
<para>
The overhead of updating the process title is much larger on Windows
than most other platforms, and it is also less useful to do it since
most Windows users do not have tools that can display process titles.

it at the <application>C</> level (Alexander Korotkov, Andrew Gierth)
</para>
<para>
This change modernizes the index <acronym>AM API</> to look more
like the designs we have adopted for foreign data wrappers and
tablesample handlers. This simplifies the <application>C</> code
and should make it more feasible to define index access methods in
and makes it much more practical to define index access methods in
installable extensions. A consequence is that most of the columns
of the <structname>pg_am</> system catalog have disappeared.
New <link linkend="functions-info-catalog-table">inspection
functions</link> have been added to allow SQL queries to determine
index AM properties that used to be discoverable
from <structname>pg_am</>.
