Tim,
I've found your message in postgres hackers list and wondering if
sourceforge db part could be improved using our recent (7.1) GiST improvements.
In short, using RD-Tree + GiST we've added index support for arrays of
integers. For example, in our rather busy web site we have pool
of online
Tim, how is PostgreSQL working for you?

I thought the hackers team would be interested in knowing that SourceForge, as
of Friday evening, is running on Postgres. Some 95,000 users and 12,500 Open
Source projects are depending on your stuff, so I hope it's
I have an index on group_id, one on
(group_id,status_id) and one on (group_id,status_id,assigned_to)
As an aside notice: you should definitely only need the last of the
three indices, since it can perfectly work on group_id
or group_id + status_id only restrictions.

btw anyone trying this query should use: "attdispersion"
I see it, yes. Was this an intended change ? I am quite sure, that it was
attdisbursion in 7.0 ?

This is great news. As far as the optimizer, any chance of testing 7.1
to see if it is improved. I believe it has been over 7.0.3.
I just did a test of my database that exhibits this behavior, using 7.1
from CVS.
When postmaster is started with "-o -fs" I get this:

Cool!
I'm running into some places where the query optimizer is not using the right
indexes, and sometimes does sequential scans on
one thing I've found to get around this is for any query that doesn't
appear to use the index properly, just do:
SET ENABLE_SEQSCAN=OFF;
query
SET ENABLE_SEQSCAN=ON;
that way for those queries that do work right, ou haven't forced it a
different route ..
