Commit 0b7719f74 added regression tests that spell the language name
as plpython3u. That works on the master branch, but on v14 the
plpython tests must use the unversioned name plpythonu: the plpython3u
extension is built only in Python 3 builds, and for those builds
regress-python3-mangle.mk rewrites plpythonu to plpython3u in the test
files. In a Python 2 build the new tests instead failed with
"language \"plpython3u\" does not exist".
Spell the language as plpythonu in the new tests, matching every other
plpython test in this branch, so they work in both Python 2 and Python
3 builds. This is needed only in v14; later branches no longer
support Python 2 and have dropped the mangling step.

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.
