My reading of this is that previously a PQgetCopyData() operation would
fail mysteriously because of

i) a reload of postgresql.conf, following the setting of any of the
following parameters client_encoding, DateStyle, TimeZone, and
standard_conforming_strings.

ii) any previous LISTEN command on the session running the COPY

Would that be correct? Did I miss anything?
