Re: large database on postgres

Stephan,
Here is more info. I don't have access to the server right now, I'll do the
explain analyze later.


table:stock_history

name    type
------------------------------
id    int         not null pk
name    varchar 250  not null  index

sql statement:

    select id from stock_history where name = "quest";
    takes about 2 minutes.


TIA,
Tony

Well, let's do the standard info requests :)
Have you used vacuum analyze?  What's the schema, query, and explain (or
explain analyze if you're using 7.2) output for the query.
