I think it would be better if the comments mentioned the function name
where the operation in question takes place rather than the file name;
for instance

and so on. I think this is more helpful for a reader because they have
a precise point to jump to instead of having to scroll through the file
looking for the place. Also this doesn't get outdated if the function
is moved to a different file (not that this happens very often.)

This could be, maybe "If ... has changed, make
StartupRequestWalReceiverRestart() aware of that." or something like
that.
