An upcoming commit will make UnlockReleaseBuffer() considerably faster and more scalable than doing LockBuffer(BUFFER_LOCK_UNLOCK); ReleaseBuffer();. But it's a small performance benefit even as-is. Most of the callsites changed in this patch are not performance sensitive, however some, like the nbtree ones, are in critical paths. This patch changes all the easily convertible places over to UnlockReleaseBuffer() mainly because I needed to check all of them anyway, and reducing cases where the operations are done separately makes the checking easier.

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.
