I have been informed that at present (postgres 7.3.2) using IN is not
advised, and I should replace it with EXISTS. I can't seem to get it to
work.
I've tried replacing (example):
SELECT
name
FROM
people
WHERE
state IN (
SELECT
id
You should use something like:
SELECT
name
FROM
people p
WHERE
exists (
SELECT
1
FROM
states
WHERE
name = p.state
)
AND state ~* 'r';

If I'm doing a reasonably sized COPY e.g. a few hundred megabytes, would
WAL segment size and number be relevant? If so any pointers on how I should
tweak stuff?
How about for speeding up many inserts?

Actually, even better:
select name
from people p, states s
where p.state = s.name
and p.state ~* 'r';

I wrote a utility once at a company where I worked previously that did this.
It did compared the meta data tables of the the two schemas. This was in
Oracle though. I think it took me less than a week to do. It might be a nice
utility to build for postgres.
It started with code as

Yeah, that's about the size of it :-(. Note though that you could

Yeah. You get something about union can't be conditionally executed

Title: pg_dump problem
I am trying to get pg_dump to work. I suspect that I am doing something wrong - Here's my command, and the resulting message.
postgres owns the database and the tables; all tables were created under postgres.
postgres has no password.
The database is named demo.
It seems the serial datatype is a frequently asked questions for novices
introduced to PostgreSQL. It appears that the competing RDBMSes are simpler
to handle in that respect, when you want to insert data and have a column
autoincremented, then fetch the value that was inserted to use in the
