Why not just saying "XXX of the PostgreSQL instance this WAL receiver is connected to"? Similarly the field names don't seem adapted to me. Would "remote" be more adapted? Other ideas are of course welcome. + char host[NAMEDATALEN]; + char hostaddr[NAMEDATALEN]; Those two should use NI_MAXHOST as maximum length. getaddrinfo() relies on that. + retval = PQconnectedhostinfo(conn->streamConn, PQ_HOST_ADDRESS); + if (retval) + *hostaddr = pstrdup(retval); Yes, going through PQconnectedhostinfo() is a good idea at the end of the day, as well as keeping one API with libpqrcv_get_conninfo(). -- Michael
