err, i included that URL but neglected to explain why. On a different
list someone suggested that I verify that there were no locks that
were blocking things, and I did so, and found no locks.
So I'm still at a loss why pg_basebackup is killing perf, and would
appreciate pointers on how to debug it or at least reduce its impact
on performance if that is possible.
