I don't really disagree. However, all the general purpose language using build
etools I found were awful. And meson's language is a heck of a lot nicer than
e.g. cmake's...

I don't immediately see a way that's not too gross (like redefining HOME when

Why not just use typmod for the underlying typmod? It doesn't seem like

- a soft error showing the error context - although that will require some

That still leaves a few logline, from before the config file parsing, but it's

at, but the make situation is
overly complicated. I don't really want to emulate having randomly differing
database names just because a test is in contrib/ rather than src/.

Nobody said anything about it not being useful to react to m_w_m changes, just
that it's not required to make some progress . So I really don't understand
what the point of your comment is.

a simple nested loop self-join, that'll prevent
the page being evicted, because it'll still be pinned on the outer side, while
generating hits on the inner side.

- tar, gzip - just for tests
I'm not sure it's worth working on not requiring those.
There's also flex, bison, perl, but those will stay a hard requirement for a
while longer... :)

Hi,
LGTM. The only comment I have is that a small test wouldn't hurt... Compared
to the other things it should be fairly easy...

A simple conversion from an existing config failed with:
Can't use an undefined va
n basis.
I think we simply shouldn't do anything here. This is a pre-existing issue. I
also think that loosing stats when turning track_io_timing on/off would not be
helpful.
