pgindent vs. git whitespace check
Commit e4602483e95 accidentally introduced a situation where pgindent
disagrees with the git whitespace check. The code is
conn = libpqsrv_connect_params(keywords, values,
/* expand_dbname = */ false,
PG_WAIT_EXTENSION);
where the current source file has 4 spaces before the /*, and the
whitespace check says that that should be a tab.
I think it should actually be 3 spaces, so that the "/*..." lines up
with the "keywords..." and "PG_WAIT..." above and below.
I suppose this isn't going to be a quick fix in pgindent, but if someone
is keeping track, maybe this could be added to the to-consider list.
In the meantime, I suggest we work around this, perhaps by
conn = libpqsrv_connect_params(keywords, values, /* expand_dbname = */ false,
PG_WAIT_EXTENSION);
which appears to be robust for both camps.

I suggest
conn = libpqsrv_connect_params(keywords, values,
false, /* expand_dbname */
PG_WAIT_EXTENSION);
which is what we typically do elsewhere and doesn't go overlength.

Maybe there's lots of data loss but the records of data loss are also lost.

Hmm, I don't think that's per project style in the first place.
Most places that annotate function arguments do it like
conn = libpqsrv_connect_params(keywords, values,
false, /* expand_dbname */
PG_WAIT_EXTENSION);
pgindent has never been very kind to non-end-of-line comments, and
I'm not excited about working on making it do so. As a thought
experiment, what would happen if we reversed course and started
allowing "//" comments? Naive conversion of this comment could
break the code altogether. (Plenty of programming languages
don't even *have* non-end-of-line comments.)

I suspect not allowing // is at least a minor annoyance to any new
developer we acquire under the age of about 40.

pgindent changes those to our style, so it's not much of an annoyance if
one prefers to type it that way during development.

Right, it's not like we reject patches for that (or at least, we shouldn't
reject patches for any formatting issues that pgindent can fix).
For my own taste, I really don't have any objection to // in isolation --
the problem with it is just that we've got megabytes of code in the other
style. I fear it'd look really ugly to have an intermixture of // and /*
comment styles. Mass conversion of /* to // style would answer that,
but would also create an impossible back-patching problem.

We could use the "use the style of surrounding code (comments)" approach - when
changing an existing commented function use the style already present; when
adding a net new function a choice can be made (unless we mandate a style). It
will still look ugly, but it will be less bad than mixing within the same
block.

Yeah, that sounds incredibly invasive.

Maybe, I've seen some mixing elsewhere and it didn't make me shudder. I
agree that you probably wouldn't want to mix both styles for end of line
comments in a single function, although a rule like that would be hard
to enforce mechanically.
Mass conversion of /* to // style would answer that,
but would also create an impossible back-patching problem.
Yeah, I agree that's a complete non-starter.

Fixed this way.

I am replying late here but ...
We would have to convert all supported branches, and tell all forks to
do the same (hopefully at the same time). The new standard would then
be for all single-line comments to use // instead of /* ... */.

That still leaves every patch which is in flight on -hackers, and conflicts in
local development trees etc. It's doable (apart from forks, but that cannot be
our core concern), but I personally can't see the price paid justify the result.

Yes, this would have to be done at the start of a new release cycle.
