Hi,
is there a newbie's FAQ / book / link for "howto optimize databases with
PostgreSQL"?
Background: Customer has the Windows* (sorry <g>) Postgres 8.1.0
standard installation "out of the box". A table has 2.5 mio records. No
indizes defined, primary key (sequence) does exist. In pgAdmin "select
count(*)" takes over 30 seconds, an "update" affecting 70'000 records
takes minutes... I am sure PostgreSQL could do better, we "just" need to
tune the database. (I hope so at least!)
What action and/or reading can you recommend? (We quickly need some
'wow' effects to keep the customer happy <sigh>).
Thanx,
Alexander.
*) sorry, I don't have server's hardware spec. available right now, but
the MSSQL2005 instance on it does the same things in a few seconds... ;-)
