Hello Alena!
As discussion here came to a halt, I want to add some
(counter)arguments, which may or may not make Michael's
proposal sound preferable to you.

As far as I understand, there should be only one to two
additional files - it's not like they will multiply.
Some extensions can use additional files, so why
pg_createsubscriber couldn't?

But if you save them as messages in server log, then user
might lose them even in verbose mode. Log is not stored
infinitely, and user may not have access to messages
if some time has passed after the incident. A file
seems to be a more reliable solution here.
P.s. About re-emitting error message with pg_fatal in my
proposal - I agree, simple exit() should suffice.
