Re: Version 7 question

Hi Hillary,

I'd suggest around 1000 to 2000 shared buffers and bump your max connections
to at least 64.

Make sure you're kernel allowed enough shared memory for the above (2000 *
8k = 16MB)

is far too low.  Would I be fairly safe in making the no of shared buffers
larger?  Also is there an equivalent of effective_cache_size that I can set
for version 7?
