I think you want to look at kdb, onetick, and LIM (those are
commercial). or potentially mongoDB where you could probably store a
compressed ts directly in the db if you want.
If you're not going to store each observation as a row, then why use a
db at all. why not stick to flat files?

I am in a similar situation described by this thread:

I need to write a few xml files to be consumed by a vendor application
in real-time. The queue / (poll/cronjob) seems simple enough.
Before I commit I just wondered if
We have Jira + Confluence on postgres. Small site (25 users). No issues.

I have a simple example copied from the 8.3 manual on partitioning
(http://www.postgresql.org/docs/8.3/interactive/ddl-partitioning.html).
My question is, if you create a serial type in the parent table which
is meant to be the primary key across all the partitions, how does one
guarantee
is that there is no explicit constraint
in the database that prevents duplicate id's from being created, and
I'm not sure how the rails app would react if for whatever reason
duplicate id keys wound up in the table.
Any suggestions?
Thanks,

Are there any integrity checks I need to run on the db after this type

I have a 300GB database, and I would like to look at partitioning as a
possible way to speed it up a bit.
I see the partitioning examples from the documentation:
http://www.postgresql.org/docs/8.3/static/ddl-partitioning.html
Is anyone aware of additional examples or tutorials on partitioning?
Is it possible to find out the OID types of the columns of a table
using the information schema?
I see that I can get the character names of the types using this query:
select * from information_schema.columns where table_name = 'my_table';
but I don't see a way to find the actual OID types of
, there is no example that uses a schema + tablename.

So, it's more like this:
select attname, atttypid from pg_attribute where attrelid = attrelid
of my table;
hmm, so how do I find the attrelid of my table
a little confused about the
internals.
