FWIW, I suspect the problem is at a much deeper level and "statistics
buffer is full" is just a minor symptom. If the stats buffer process is
stuck, that should really have no effect on the system other than
failure to deliver statistics updates. Probably the reason why it's
reporting this is that the stats collector process is stuck, and perhaps
the underlying reason for that is also affecting regular backends. But
there's not nearly enough info here to diagnose the true cause.
In any case I agree with Alvaro that 8.1.3 is horribly obsolete,
and you should at least update to the end of the 8.1 release branch
if you can't easily migrate to a supported branch.
