I have only noticed that after a VACUUM ANALYZE of the db the time of a seq scan (when
a seqscan is required) has increased by a factor of ten, this is my primary focus,
otherwise I would have posted something about "my select is really slow ..."

To be more precise: 
Given a query that HAS to be executed with a seqscan I have noticed an increase in
time comparing before and after the vacuum.


Anyway I am working to create the same situation again to post some output of the
verbose option of the vacuum.
