Thread: Need help on autovacuum in postgres 9.1.2
Hi
I need help in turning off autovacuum in the Database that’s running postgres 9.1.2 DB. I tried to turn it off by putting “off” in postgresql.cont file and restarted the postmaster but when I run “show autovacuum; “ query I still see autovacuum set on inside the database.
autovacuum
------------
on
(1 row)
postgresql.conf currently looks as follows. Should I remove the hash sign that’s before “autovacuum = off” ?
#autovacuum = off # Enable autovacuum subprocess? 'on'
#log_autovacuum_min_duration = -1 # -1 disables, 0 logs all actions and
#autovacuum_max_workers = 3 # max number of autovacuum subprocesses
#autovacuum_naptime = 1min # time between autovacuum runs
#autovacuum_vacuum_threshold = 50 # min number of row updates before
#autovacuum_analyze_threshold = 50 # min number of row updates before
#autovacuum_vacuum_scale_factor = 0.2 # fraction of table size before vacuum
#autovacuum_analyze_scale_factor = 0.1 # fraction of table size before analyze
#autovacuum_freeze_max_age = 200000000 # maximum XID age before forced vacuum
#autovacuum_vacuum_cost_delay = 20ms # default vacuum cost delay for
# autovacuum, in milliseconds;
#autovacuum_vacuum_cost_limit = -1 # default vacuum cost limit for
# autovacuum, -1 means use
Please assist.
Thanks

That's almost never the right thing to do; if anything you should usually be turning it *up*. -- Craig Ringer
