I am going to install Postgresql 9.0 for my running applicaiton which is at
8.1.
My Db size is 3 GB.
Server Specification:
dual-core 4 cpu
RAM: 32 GB
OS: Centos
What will be good settings for DB parameters such as shared_buffers,
checkpoint_segment and etc.
Any help please.

Hello,
When reindexing we keep the previous and new reltuples/relpages ratio in
in a reference table in order to track the reindex efficiency.
We also have a maintenance jobs that compare this table with the stats
from pg_class and automatically reindex the relations where the ratio
degraded t
For now I just ignore the first exception.

ZFS has an option to use an SSD as cache for the spinning drives. ZFS
under Solaris has turned in some really good IO numbers. The problem is
with the new Sun I am not feeling so good about the open nature of
Solaris. ZFS performance under BSD I have read does not match ZFS under
Solaris.

I've got an odd problem. I've got a column with a non-standard
date/time in it that I carve up and re-cast as a timestamp. This works
fine. Now though, I am trying to check/restrict my results to dates
before now() and it's telling me that the columns doesn't exist.

You can't refer to a column alias name in the order by clause

Generally, wanting more than a few dozen columns is a good sign that you
need to rethink your schema design. What are you trying to accomplish

Hey Mark,
Yeah, I can't imagine an entity in a real project even with more than 100
columns. Its rare case.
But if you entities (rows/tuples) of some class (table) can contains
variable
set of columns (properties) you can look at hstore contrib module.

Hey Peter,
Unfortunately, there is no indexes on arrays (only on expressions).
With hstore we can easily create GiST index for effective access.
