Hello All,
I have a setup with a Dell Poweredge 2650 with Red Hat and Postgres 7.4.5 with
a database with about 27GB of data. The table in question has about 35 million
rows.
I am running the following query:
SELECT *

WHERE msg_client_order_id IN (

It seems that you could combine the subquery's WHERE clause with the main
query's to produce a simpler query, i.e. one without a subquery.
Rick
Actually, unfortunately, that won't work. The subquery gets a list of message
IDs and then the outer query gets the responses to those messages.
Also, I dumped this data and imported it all to ms sql server and then ran it
there. The query ran in 2s.

I will run EXPLAIN ANALYZE when I can. I started running the query when I sent

locations?
Given that the free space map is global, and it is ostensibly managing
free disk space, how does it deal with tuples across disk locations ?

Andrew,
Dell's aren't well known for their disk performance, apparently most of
the perc controllers sold with dell's are actually adaptec controllers.
Also apparently they do not come with the battery required to use the
battery backed up write cache ( In fact according to some Dell won't

It doesn't really care. It identifies tables by database OID+table OID,
and where they happen to sit physically doesn't matter.

No, have a look at the create database command
there is a clause 'with location' that allows you to set up a separate
location for the db

If certain databases have more

So What does memcached offer pgsql users? It would still seem to offer
the benefit of a multi-machined cache.
Ack, I totally missed this thread. Sorry for jumping in late.
Basically, memcached and pgmemcache offer a more technically correct
way of implementing query caching. MySQL's query
