Should effective_cache_size include the size of shared_buffers? Also,
FreeBSD doesn't seem to want to use more than about 300M for disk
caching, so I currently have shared_buffers set to 90000 or about 700M
(the box has 2G, but pgsql currently has to share with Sybase). Are
there any issues with setting shared_buffers so high? Anyone know how to
make FBSD do more caching on it's own, or should I just let pgsql handle
it?
