Hi list,
I'd like to ask you if you have any experience with some solution or how do
you manage tasks described below.
We have tens of separate databases (for different apps and purpose) which
we want send regular tasks to. The tasks are always SQL queries, for
example count some bilance after

could someone explain what exactly node mean in postgres.
You can think of it like a simple abstract base class that everything
else extends.
Lots of PostgreSQL is pseudo-object-oriented, so you'll see this pattern
around a fair bit.

Hi.
I was wondering how come there is such a drastic difference between finding
max and min. Seems like index scan backwards is really bad... The table
is freshly re-indexed just in case. I added a count(*) in there, forcing
the seq scan, and it's even better than the backwards index scan...

It's probably an artifact of your data distribution, ie, the blockid =
4814 condition is skipping lots of rows

Hi Jonathan,
I'm really interested in the type of hybrid architecture you've mentioned.
How is the read-only index constructed in the design you're mentioning?
It'd be much appreciated if you could briefly describe the order of

Rather than chunking out blocks, set an increment value for each sequence equal

BTW, looking at your example, you might be more interested in ranges,
see for example:
http://www.postgresql.org/docs/9.2/static/rangetypes.html
Conceptually they are a bit different and there isn't support for
multi-ranges AFAIK
You could have an array of ranges
