I have a question for Data Warehousing / Business Intelligence users, is
64-bit support to allow large in-memory buffer cache within Postgres
important?

There is a patch contributed by Koichi Suzuki of Nippon Telecom that shows
very good results.  It extends the buffer cache of 8.0.3 to 64-bit, allowing
for caches larger than 2GB.  See "[PATCHES] A couple of patches for
PostgreSQL 64bit support" in the pgsql-patches list for details.

We could adopt this patch within Bizgres and test it, should this be a
desirable feature.

Thoughts?
