I'm just trying to improve performance on version 7 before doing some tests and 
hopefully upgrading to 7.3.

At the moment we have 
B=64  (no  of shared buffers)
N=32 (no of connections)
in postmaster.opt which I take it is the equivalent of the new postgresql.conf file.

 From all that is being written about later versions I suspect that this 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?

Many thanks in advance
