Tom Lane 5cbfce562f Initial pgindent and pgperltidy run for v13.
Includes some manual cleanup of places that pgindent messed up,
most of which weren't per project style anyway.

Notably, it seems some people didn't absorb the style rules of
commit c9d297751, because there were a bunch of new occurrences
of function calls with a newline just after the left paren, all
with faulty expectations about how the rest of the call would get
indented.

This directory contains tools to generate the tables in
src/include/common/unicode_norm.h, used for Unicode normalization. The
generated .h file is included in the source tree, so these are normally not
needed to build PostgreSQL, only if you need to re-generate the .h file
from the Unicode data files for some reason, e.g. to update to a new version
of Unicode.

Generating unicode_norm_table.h
-------------------------------

Run

    make update-unicode

from the top level of the source tree and commit the result.

Tests
-----

The Unicode consortium publishes a comprehensive test suite for the
normalization algorithm, in a file called NormalizationTest.txt. This
directory also contains a perl script and some C code, to run our
normalization code with all the test strings in NormalizationTest.txt.
To download NormalizationTest.txt and run the tests:

    make normalization-check

This is also run as part of the update-unicode target.
