I have been trying for a week now without success to discover
if you can measure the cost of a query (with my c function).
EXPLAIN ANALYZE seems to give you the actual time it took it
to run but the "cost" seems to be a fixed estimate number and not
actual. I see in the code many times references t

Not sure what overhead - but Oracle has this ;) Infact Oracle by
default puts each user in their own schema, and each user can be
assigned a default tablespace as a property of the user. With the
advent of Tablespace in pg 8.0, is it possible to set a user's default
tablespace?

No offense or anything, but that doesn't make any sense. If you are
running count(*) against a table, it still has to worry about MVCC,
and which rows are visible to your transaction. What difference does
it make, table or index, the system still has to figure out which rows

hello to all
Soon time I am going to face a migration of a DBII
database our dear poststoneware. I will thank for any
advice that can give me, in addition this migration
will have 20 million records.
20 million record is to large instalation, exist some
tips for this type of facilities?

I know that this is off topic, but I'm not getting anywhere and wondered
if anyone has come across and solved this problem before.
We use Nagios to monitor our servers. Our Dell PE 1550s and 1750s are
monitored using a check_megaraid nagios plugin which uses SNMP and works
fine.

I must not have been clear. In postgres you can limit people to a
tablespace (in 8.0 of course). You do this by giving them a database
with a default tablespace, and only give them permission on that default
tablespace. That works fine.
The problem is, there is no limit to the size of a tablespace
I've written a c-language extension to postgresql to implement a
chemical search of a varchar column (named smiles, typically).
It might be called as:
oe_matches(smiles,'COCC') where 'COCC' is a typical search string.
This uses 3rd party functions to parse the varchar inputs into c++
objects. I
We're looking into building a front end for our database in python.
The database in question is an educational database, that generates
new tables for each teacher, class and student. Was wondering if
anyone had any recommendations for similar projects to look at,

I gather your program uses two steps, let's call them :
- parse( smiles ) -> data
- search( data ) -> result
You can create a functional index on your smiles column, but I don't know
if this will help you ; you can do things like CREATE INDEX ... ON

Never used ODBC with Python, but if you want to use Postgres, I'd
strongly recommend psycopg which I find the nicest and fastest postgres
adapter (certainly a lot better than Pygresql and pypgsql)

(The example is really count(pkey) because count(*) is always going to
do a seq scan I reckon - and could probably never use an index).
postgres knows that count(*) is just "count the rows", you can use
count(1), it makes no difference...

Is there a maximum size for posting to this list? I tried posting a
somewhat involved question about PITR with the errors I got appended to

I would still like to get my question answered, but it's hard to ask

For record types, why not just use cursors? They can be made to persist

I've looked into pshycho pg, it appears to be the best option, my later question
now remains, what documentation or examples would be useful in developing a
completely proprietary front end written in python. Any help finding useful
examples or documentation would be greatly appreciated.
