Обсуждение: fsync off without a restart

Hi list,

I have got a script that is inserting, updating heavily at the moment. So, I want to turn fsync off to speed things up
butI don't want to interrupt the script. 

If I do `postgresql reload` or `kill -HUP postmaster_pid` woudl that apply the fsync change? By the way, I have already
triedit and seems that it has worked. 

But I have got another question. On my debian system I have got `postgresql force-reload`. How does that differ from
theplain reload? And what does it actually do under the hood? 

I am running Postgres 8.1.11 on Linux 2.6.18.

Regards,

Val

If you're referencing to the init script (/etc/init.d/postgresql-XXX),
then they should be the same stuff.
