how do I write a query that will give me the resultset:

I.E. for each distinct val, return the record with the most recent date.
Isn't it something simple like

Hello,
I asked this question on JDBC list, but it seems dead.
I found alternative JDBC driver marked as Beta 2 (actually last time
bumped to Beta 2.1) http://softperience.eu/pages/cmn/ngpgjdbc.xhtml.

Yes. I would be excited to know if there is a possibility of multi-master
replication system on Postgres.
We will be soon using 9.1 Streaming replication.

Hello.
This might be the wrong place to post my question, but any help is appreciated.
Did any one used Jenkins for Postgresql unit testing, and what are the
available unit testing plug-ins?, is there is a tutorial for that ?
Thanks in advance

Dear all,
first let me thank the PostgreSQL developers for implementing the incredibly
helpful window functions. This is one of the features I use most often.
But, as my requirements are perhaps a bit special, I always want more ;)
Now I am trying to implement my own window function using
I would think to do it like
SELECT DISTINCT ON (val) val,date ORDER BY date DESC, val ASC
I haven't tested this, but it's similar to things I've done recently,
and I'm pretty sure this will do what you want.

I've got a large table that has 15 million + rows in it, and a set

These queries basically do a 'select max(primary_key_column) from table

I'm sorry Reid, driving back home I realized that the previous query I
suggested didn't do what I was expecting, cause it would compute all of val2
for each val1, even if they belonged to another group (not for a particular
val1/date pair), or in other words, to another date.
I've considered this
