Continuing the discussion from [0] and [1], here is a patch that
automates the process of updating Unicode derived files. Summary:
- Edit UNICODE_VERSION and/or CLDR_VERSION in src/Makefile.global.in
- Run make update-unicode
- Commit
I have added that to the release checklist in RELEASE_NOTES.
This also includes the script used in [0] that was not committed at that
time. Other than that, this just refactors existing build code.
Open questions that are currently not handled consistently:
- Should the downloaded files be listed in .gitignore?
- Should the downloaded files be cleaned by make clean (or distclean or
maintainer-clean or none)?
- Should the generated files be excluded from pgindent? Currently, the
generated files will not pass pgindent unchanged, so that could cause
annoying whitespace battles when these files are updated and re-indented
around release time.

Subject: [PATCH] Add support for automatically updating Unicode derived files
We currently have several sets of files generated from data provided
by Unicode. These all have ad hoc rules and instructions for updating
when new Unicode versions appear, and it's not done consistently.
This patch centralizes and automates the process and makes it part of
the release checklist. The Unicode and CLDR versions are specified in
Makefile.global.in. There is a new make target "update-unicode" that
downloads all the relevant files and runs the generation script.
There is also a new script for generating the table of combining
characters for ucs_wcwidth(). That table is now in a separate include
file rather than hardcoded into the middle of other code. This is
based on the script that was used for generating
d8594d123c155aeecd47fc2450f62f5100b2fbf0, but the script itself wasn't
committed at that time.
