similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonably complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonably complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonably complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonably complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

* [PATCH v16 05/10] pg_ls_tmpdir to show directories and "isdir" argument..

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.
Need catversion bump

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonably complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

* [PATCH v16 05/10] pg_ls_tmpdir to show directories and "isdir" argument..

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonbly complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

Hm. I don't find it particularly confusing, but I don't think I'm a good judge
of that, too close.

It'll work, but only if you have run setup before. And it'll not use changed C
code.
The setup suite creates the installation in tmp_install/. So if you haven't
run the tests before, it'll fail due to that missing. If you have run it
before, but have changed code, it'll not get used.
The background for the issue is that while meson test supports dependencies
for each test, and will build exactly the required dependencies if you run
individual tests with meson test, it unfortunately also adds all the test
dependencies to the default ninja target.
That's mostly for historical reasons, because initially meson didn't support
dependencies for tests. There's recent work on changing that though.
Creating the temp installation every time you run 'ninja' would not be
nice. On slower machines it can take quite a while.
I think medium term we should just stop requiring a temporary install to run
tests, it's substantial, unnecessary, overhead, and it requires us to build
way too much to run basic tests. It'd not take a whole lot to make that work:
- a search path for finding extensions, which'd be very useful for other
reasons as well
- a way to tell 'postgres', 'initdb' etc, which use find_other_exec(), that
they should use PATH
- a way to tell initdb where to find things like postgres.bki, postgres where
it can find timezone data, etc.

I see. It's not that confusing on its own, but it does cause confusion
once you consider how things fit together. Suppose I want to do the
equivalent of running the amcheck tests -- the tests that run when
"make check" runs from contrib/amcheck with an autoconf build. That
looks like this with our current meson workflow:
meson test -v --suite setup --suite amcheck
Now consider what I have to run to get the equivalent of a "make
installcheck" run from the contrib/amcheck directory:
meson test -v --setup running --suite amcheck-running
Notice that I have to specify "--suite setup" in the first example,
whereas I have to specify "--setup running" in the second example
instead -- at the same point in. Also notice the rest of the details
almost match. This makes it quite natural to wonder if "--suite setup"
is related to "--setup running" in some way, which is not the case at
all. They're two wholly unrelated concepts.
Why not change the suite name to tmp_install? That immediately reminds
me of what's really going on here, since I'm used to seeing that
directory name. And it clashes with "--suite setup" in a way that
seems useful.

The individual test is actually named tmp_install. I thought it might be
useful to add further things to the setup "stage", hence the more general
name.
I e.g. have a not-quite-done patch that creates a "template initdb", which
pg_regress and tap tests automatically use (except if non-default options are
required), which quite noticably reduces test times (*). But something needs to
create the template initdb, and initdb doesn't run without an installation, so
we need to run it after the temp_install.
Of course we could wrap that into one "test", but it seemed nicer to see if
you fail during installation, or during initdb. So for that I added a separate
test, that is also part of the setup suite.
Of course we could still name the suite tmp_install (or to be consistent with
the confusing make naming, have a temp-install target, which creates the
tmp_install directory :)). I guess that'd still be less confusing?
I'm not at all wedded to the "setup" name.

The 4x reduction in CPU cycles is pretty bonkers. To bad wall clock time

I expect it to very substantially speed up the valgrind builfarm animal. By
far the most cycles are spent below initdb.

I did notice that, but only after sitting with my initial confusion for a while.

But what are the chances that the setup / tmp_install "test" will
actually fail? It's almost a test in name only.

Yes, that definitely seems like an improvement. I don't care about the
tiny inconsistency that this creates.
I wonder if this could be addressed by adding another custom test
setup, like --setup running, used whenever you want to just run one or
two tests against an ad-hoc temporary installation? Offhand it seems
as if add_test_setup() could support that requirement?

I've seen more failures than I'd like. Permission errors, conflicting names,
and similar things. But mainly that was a reference to running initdb, which
I've broken temporarily many a time.

Then lets do that - feel free to push something, or send something for
review. Otherwise I'll try to get to it, but I owe a few people work before
this...

What precisely do you mean with "ad-hoc temporary installation"?
I was wondering about adding a different setup that'd use the "real"
installation to run tests. But perhaps that's something different than what
you have in mind?
The only restriction I see wrt add_test_setup() is that it's not entirely
trivial to use a "runtime-variable" path to an installation.

We've all temporarily broken initdb literally thousands of times, I'm sure.

I'll try to get to it soon. Note that I've been adding new stuff to
the meson Wiki page, in the hope of saving other people the trouble of
figuring some of these details out for themselves. You might want to
take a look at that at some point.

I mean "what make check does".

I wasn't thinking about the installation. Actually, I was, but the
thought went no further than "I wish I didn't have to think about the
installation". I liked that autoconf had "make check" and "make
installcheck" variants that worked in a low context way.
It's great that "meson test" runs all of the tests very quickly --
that should be maintained, even at some cost elsewhere. And it would
be nice to do away with the tmp_install thing. But as long as we have
it, it would be nice to make the way that we run a subset of test
suites against a running server similar to the way that we run a
subset of test suites against a throwaway installation (ala "make
check").

I personally have no problem with that, though of course I could have
easily overlooked something.
