This old CPU architecture hasn't been produced in decades, and whatever instances might still survive are surely too underpowered for anyone to consider running Postgres on in production. We'd nonetheless continued to carry code support for it (largely at my insistence), because its unique implementation of spinlocks seemed like a good edge case for our spinlock infrastructure. However, our last buildfarm animal of this type was retired last year, and it seems quite unlikely that another will emerge. Without the ability to run tests, the argument that this is useful test code fails to hold water. Furthermore, carrying code support for an untestable architecture has costs not to be ignored. So, remove HPPA-specific code, in the same vein as commits 718aa43a4 and 92d70b77e. Discussion: https://postgr.es/m/3351991.1697728588@sss.pgh.pa.us
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.
