Hi
I am currently running a vacuum analyse through PgAdmin on a PostgreSQL
8.1.9 database that takes forever without doing anything: no
(noticeable) disk activity or (noticeable) CPU activity.
The mesage tab in PgAdmin says:
...
Detail: 0 index pages have been deleted, 0 are currently reusable.
CPU 0.01s/0.00u sec elapsed 568.16 sec
....
and lots of entries looking just like this ( 0 % CPU, > 500 secs).
There are no other connections to the database and the machine does not
do anything else than me typing this e-mail and playing Metallica MP3's.
Could this be because of my Cost-Based Vacuum Delay settings ?
vacuum_cost_delay = 200
vacuum_cost_page_hit = 6
#vacuum_cost_page_miss = 10 # 0-10000 credits
#vacuum_cost_page_dirty = 20 # 0-10000 credits
vacuum_cost_limit = 100
