Looking at  "top" we  saw the postgres  process growing and  growing and
then shrinking  back, and doing  a "select * from  pg_stat_activity;" in
parallel of the growing we found only the "vacuum analyze" query running.

But maybe  we drawn the conclusion  too quickly, I'll  try disabling the
auto vacuum to see if we really get rid of the problem doing it.

Thanks for your answers.
