Mark Rae did some tests on SMP scaling for PostgreSQL and found that
CVS TIP is an improvement over 8.0.1.  Details in this thread:

Christopher Kings-Lynne has developed a set of new PHP access function
for PostgreSQL to support our v3 protocol, which should improve
performance of PostgreSQL-PHP.  There was a small legal hitch with the
requirement to re-license parts of the PostgreSQL documentation to
PHP, but that's being resolved.

Satoshi Nagayasu volunteered to work on the "Read-Only Database" TODO

There was an extensive, around how to invalidate cached query plans
which have outlived their usefulness.  The product of this was Neil
Conway proposing work on a query planner overhaul that would store its
plan in a fashion that interferes less with our plan caching; however,
the exact architecture of this is not yet determined.

Magnus Hagander has written an addition to the website to database the

Merlin Moncure proposed a patch to hide the function source in the
pg_proc table from unprivileged users, which was opposed by Tom Lane

Tom Lane has discovered that the patch to pg_was he added for 8.0 to
detect a dead lockfile situation on startup was inadequate and is
being re-written.

Michael Fuhr discovered the following cryptic remark in our source
    From src/backend/tcop/postgres.c:
     /* they only drink coffee at dec */
If you know what this comment means, please mail  and
we'll publish your explanation next week.

Tom Lane proposed an implementation of a "Local Buffers" feature to
allow allocation of per-user buffers specifically for holding
temporary tables.

The pgsql-performance mailing list had extensive discussions on the
query planner parameter model, how to read a query plan, and
correlated cost estimation for multi-column indexes.

WWPI (Weekly Windows Port Issue):
Andrew Dunstan reported that contrib/pg_buffercache is apparently
broken on Windows.  A patch for the issue was posted but has not yet
been tested/merged.
