We're looking to deploy a bunch of new machines.
Our DB is fairly small and write-intensive. Most of the disk
traffic is PG WAL. Historically we've avoided
RAID controllers for various reasons, but this new deployment will be
done with them (also for various reasons ;)
We like to use white-boxis

I guess you could call Highpoint a RAID manufacturer, but I wouldn't do
so. They've released so many terrible problems over the years t

I know I can setup a FK constraint to make sure Table1.ColA exists in
Table2.Key, however what if I want to do the reverse?
I want to ensure Table1.ColA does NOT exist in Table2.Key.. Can I do
this with any sort of CHECK constraint, trigger, custom function, etc?

I'm working with a product that uses effective date based data structures. We
then create views using analytic functions that have begin and end dates for
when that record was valid. This works fine when there is just one record per
item that is valid at any given time (for instance job assignme

No responses to my earlier post, I'm assuming because OS X experience is rather

1) Is my impression correct that given a choice between Areca & Highpoint, it's
a no-brainer to go with Areca?
2) I understand why RAID 5 is not general

Hi, I'm used to work with PostgreSQL on Windows but now I've moved to OS X
and I'm having problems to create a service to auto start a new server
(instance) of PostgreSQL.
Firstly I used the PostgreSQL installer to create the first server and the
postgres user, then I used initdb to create another
We are expecting following advantages through this,
Unauthorized use either by the
1. DB administrator
2. ex-developer Or
3. Any body
This why PostgreSQL has the concept of "ROLE"s.
The data, not the schema, is what needs to be secured.you are not preventing
unauthorized use only
