Thanks for clarifying what the current variable declaration indention
rule is. Indeed neither uncrustify or clang-format seem to support
that. Getting uncrustify to support it might not be too difficult, but
the question remains if we even want that.

I don't think the amount of pain is really much lower if we reformat
10,000 or 300,000 lines of code, without automation both would be
quite painful. But the git commands I shared in my previous email
should alleviate most of that pain.

Function parameter alignment is fine with pgindent imho, but this +12
column variable declaration thing I personally think is quite weird.

It seems this was due to my Ubuntu 22.04 install having clang-format
14.0.0. After
updating it to 14.0.6 by using the official llvm provided packages, I
don't have this
issue on clang-format-14 anymore. To be clear this was an issue in alignment of
variable declarations not function parameters.

But I agree with Tom Lane that this makes clear that whatever tool we
pick we'll need
to pick a specific version, just like we do now with perltidy. And
indeed I'm not sure
how easy that is with clang. Installing a specific uncrustify version
is pretty easy btw,
the compilation from source is quite quick.
