The actual problem with this change request is that it's wrong.
We've supported changing ssl_cert_file --- either the GUC value
or the file contents --- via "pg_ctl reload" or equivalent for
years now (cf. commits de41869b6, 6667d9a6d).  So I don't see
anything wrong with the docs text as it stands.
