Hello.
I have a question about perfomance.
I'm running PostgreSQL 7.1.2 at FreeBSD 4.3.
For the first 1-2 days of running perfomance is excellent. But
after that, speed began to decrease. And after a week of
operation, perfomance falls 8-10 times,
A question has intrigued me ever since I started to learn about Berkeley
DB (well after I had started using postgres): does PostgreSQL seperate
the data management routines such that I could use them in a way similar
to Berkeley DB? I find the concept useful for people who don't want to
start

It sounds to me like you may be running into index growth problems.
VACUUM is presently not good about shrinking indexes.
