Hi Peter,
Thanks for your reviews. I tried to apply most of them. I just have
some comments below for some of them.

I agree that these explanations at places where the worker decides to
not continue with the current table were confusing. Even the name of
ready_to_reuse was misleading. I renamed it and tried to improve
comments in such places.
Can you please check if those make more sense now?

I'm not really against moving those functions to tablesync.c. But
what's not clear to me is worker.c. Is it the places to put common
functions for all log. rep. workers? Then, what about apply worker?
Should we consider a separate file for apply worker too?
Thanks,
