Hello..

I was wondering if it's possible to make postgresql backend to adjust his priority based by an parameter to begin..

i.e: For linux , a "BEGIN -20" to renice backend priority to -20..

This should be easy (i hope) to implement using setpriority(..) , but there are a few questions.

1) How portable is it ?

2) What implications does it have on the postgres backend ?

This could be useful in some situations (like logtables , where I don't need instant inserts or updates..)

Thanks

Alex
