Probably an optimistic question - can a user with access to two
databases create a function in one to access tables in the other? Or
triggers?

I am trying to force a column to have lowercase because Postgresql is
case-sensitive in queries. For the time being I've made an expression
index on lower(KEY). But I would like to have just lower case data and
then drop this expression index.

I suspect you're not showing us the exact queries you're running. For
one, you can't have a table named TABLE (without quotes) in PostgreSQL.
Of course. The data is a tad private, hence the simple table and
column names represented in uppercase.
Perhaps something else you changed when

Hello,
Imagine a web application that process text search queries from

you do a lot of queries like that and the id,s_id restriction isn't very
selective you might look into tsearch2 which can index that type of query.
Thanks. Does tsearch2 come installed with 8.2.3? I am not techie
enough to do all the compiling stuff so I'm hoping it does! How can I
check?
I'm grappling with a lot of reporting code for our app that relies on
queries such as:
SELECT COUNT(*) FROM TABLE WHERE (conditions)...
And I still do not find, from the discussions on this thread, any
truly viable solution for this. The one suggestion is to have a
separate counts

In some examples posted to this forum, it seems to me that when people
execute queries in the psql window, they also see 90 ms taken
(milliseconds), which denotes the time taken to execute the query.
Where can I set this option because I'm not seeing it in my psql
window on both Win XP and Linux.
