Hi,

It looks like comments in make file and meson file about not running
basic_archive tests in NO_INSTALLCHECK mode are wrong. The comments say the
module needs to be loaded via shared_preload_libraries=basic_archive, but
it actually doesn't. The custom file needs archive related parameters and
wal_level=replica. Here's a patch correcting that comment.

Thoughts?

Wouldn't it be better to also set shared_preload_libraries in
basic_archive.conf? It is true that the test works fine if setting
only archive_library, which would cause the library with its
_PG_init() to be loaded in the archiver process. However the GUC
basic_archive.archive_directory is missing from the backends.

Saying that, updating the comments about the dependency with
archive_library and the module's GUC is right.

Hm, I think the other backends will still see the value of the GUC
without shared_preload_libraries=basic_archive. You can verify it with
adding SHOW basic_archive.archive_directory; to basic_archive.sql. The
basic_archive library gets loaded by archiver via _PG_init. It's the
archiver defining a custom GUC variable which will propagate to all
the postgres processes via set_config_option_ext. Therefore, we don't
need shared_preload_libraries=basic_archive.

Thanks. Any thoughts on the v1 patch attached upthread?

Reworded the comment a bit and attached the v2 patch.

Forgot about this one, thanks! I've simplified it a bit and applied
it.
