Re: Re: Re: "--tuning" compile and runtime option (?)

Well, what is being discussed here would require a *recompile* to change the
values, so you sure wouldn't want that! :-)

Currently you can set a lot of internal variables with the SET command in any PG
session.. It's useful for forcing index or sequential scans and such (and I'm
sure a lot more)..
