RE: Incorrect CONTEXT reported for errors from parallel apply worker in logical replication

Hi Ideriha-san,

Thanks for the review. PSA v4 patch set.

I think the current code won't be included to core, thus we do not take care
the shape of meson.build (I have tested with fixing it locally).
But it might be better to add for the cfbot. Done.
Also, I found the test sometimes could not launch the parallel apply worker
because of the race condition with the table synchronization. I set to
copy_data = false instead.

Indeed, removed. I have not checked well due to the above reason.
