Up to now, we've only worried about whether tests running in parallel

that the meson setup has expanded the possibility of interactions
to our entire source tree.  Maybe that was a bad idea and we should
fix the meson infrastructure to not do that.  I fear that otherwise,
we'll get bit regularly by very-low-probability bugs of this kind.

I have the same concern.  I suspect that the scan of pg_prepared_xacts
is not the only test that could cause problems when running in parallel
to other tests from the entire source tree.

Thanks
