If you have enough connections, then that seems unnecessary.

The *opposite* would be true; if you change max connections, you might
need to change the size of the shared buffer...

At any rate, if you actually want substantive improvements in
performance, I would *highly* advise moving to a version of PostgreSQL
that is *way* newer, like version 8.1. There are *enormous* numbers
of improvements that affect performance between 7.3 and 8.1.

inadequate set of requirements, and that you can have reasonably
strong confidence that this is the case." -- Jonathan S. Shapiro
