Hi hackers.
There is ineresting behavior of some select query mentioned in $subj.
In working db this query takes:
real 3m10.219s
user 0m0.074s
sys 0m0.074s
it's interesting that vacuum or analyze or reinex not helpfull, BUT
if dump this db and create it again (whith another name mabe, no matter,
just for testing) and query the same query on this db, it takes:
real 0m6.225s
user 0m0.072s
sys 0m0.074s
(other databases continue running)
There is no end of this story!
With some time (couple of days for example) this the same query overloads
machine on this new test db also! No one working with this db during this
time. Works continued only with real working databases. Vacuuming was
as usual (every 2 hours without -f and with it at night one time :) :
as i said this behavior does not depend on any vacuuming.
Have anyone any ideas about this?
