Not quite a performance question, but I can't seem to find a simple answer to this. We're using 8.1.4 and the autovacuum daemon is running every 40 seconds cycling between 3 databases. What is the easiest way to disable the autovacuumer for a minute or two, do some other work, then re-enable it? Do I have to modify
postgresql.conf and send a HUP signal to pick up the changes?
I figured this would work but I can't find a reason why not:
# show autovacuum;
autovacuum
------------
on
(1 row)
autovacuum
------------
on
(1 row)
# set autovacuum to off;
ERROR: parameter "autovacuum" cannot be changed now
In postgresql.conf:
autovacuum = on
Thanks,
Steve
