In pg_log_generic(), be more paranoid about preserving errno. This code failed to account for the possibility that malloc() would change errno, resulting in wrong output for %m, not to mention the possibility of message truncation. Such a change is obviously expected when malloc fails, but there's reason to fear that on some platforms even a successful malloc call can modify errno.
