The message is in src/backend/postmaster/pgstat.c:
if (!overflow)
{
ereport(LOG,
(errmsg("statistics buffer is full")));
overflow = true;
}
For log_min_messages, LOG is just above FATAL and PANIC, so I'd
expect those messages to appear in the logs if they're happening.
But I don't recall seeing them either.

I was also able to reproduce the behavior when running pgbench with
sufficiently high settings.
