Hello,
I'm still at beginning regarding databases. I got a question about trigers
that model the behavior of some data,
usualy a relational database may contain trigers and declarative sql
constraints.
My question is how could I detect these trigers within a database?
using postgresql would help
Hi,
do you want to know how to create a trigger?
http://www.postgresql.org/docs/9.0/interactive/sql-createtrigger.html
http://www.postgresql.org/docs/9.0/interactive/sql-createtrigger.htmldo
you want to know how to list the triggers in your database?
- in pgAdmin they are listed in the tree-view
I'll leave the can/cannot responses to those more familiar with
high-load/use situations but I am curious; what reasons other than cost are
leading you to discontinue using your current database engine? With that
many entities any migration is likely to be quite challenging even if you
maybe this?

Which type of data type will be used in above function (in place of ?)
that can collect more than one row(20,000) ?
Maybe the id that those 20M records have in common?

A developer here accidentally flooded a server with connection opens and
closes, essentially one per transaction during a multi-threaded data
migration process.
We were curious if this suggests that connection clean up is more
expensive than creation thereby exhausting resources, or if perhaps
After upgrading to pg 9.0.3 (from 8.4.2) on my Mac OS 10.6.2 machine i find
this in my log file (a lot):
postgres%192.168.254.210%2011-03-03 16:37:30 CET%22021STATEMENT: SELECT
pg_file_read('pg_log/postgresql-2011-03-03_00.log', 25, $
postgres%192.168.254.210%2011-03-03 16:37:32
top posting my self to clarify, since the title is in fact inverted:
close might be more expensive the open.

Hey folks,
I was looking through the contrib modules with 8.4 and hoping to find
something that satisfies my itch.

I'm inheriting a database which has mostly unknown usage patterns, and would
like to figure them

Aha! Thank you.
Given the below information, is it reasonable to assume that files in pgsql_tmp
dated prior to 10 days ago can be safely removed?

That listing doesn't show anything in pgsql_tmp ...
What the listing looks like to me is a tablespace containing a few

In and of-itself sheer number of rows only hits you when you need to be
reading most of them; in that case good hardware
