pg_receivewal and messages printed in non-verbose mode

Hi all,

I have noticed that the following messages can show up from
pg_receivewal even if the verbose mode is not used:
if (prevtimeline != 0 && prevtimeline != timeline)
fprintf(stderr, _("%s: switched to timeline %u at %X/%X\n"),
progname, timeline,
(uint32) (prevpos >> 32), (uint32) prevpos);
if (time_to_abort)
{
fprintf(stderr, _("%s: received interrupt signal, exiting\n"),
progname);
return true;
}
Those come from stop_streaming in pg_receivewal.c. Shouldn't those
messages only show up to the user if --verbose is used? It seems
strange to me that at least the first one is written to the user as
that's not an error after promoting a standby.

Thanks,
