The following changes are done: - Addition of WaitEventBufferPin and WaitEventExtension, that hold a list of wait events related to each category. - Addition of two functions that encapsulate the list of wait events for each category. - Rename BUFFER_PIN to BUFFERPIN (only this wait event class used an underscore, requiring a specific rule in the automation script). These changes make a bit easier the automatic generation of all the code and documentation related to wait events, as all the wait event categories are now controlled by consistent structures and functions.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
