pg_dump dumps data first and then the constraints (including FK) so
there shouldn't be any problems when you import the dump.

Speaking of timestamps, I think it would be convenient to have a
single-word alias for timestamp with time zone. This is the date
type I use almost exclusively and its name is annoyingly big.

Another issue to keep in mind is that in POSIX time zone names,
positive offsets are used for locations west of Greenwich.

MySQL had the following syntax available:
`updated_date` timestamp NOT NULL default CURRENT_TIMESTAMP on update
CURRENT_TIMESTAMP
I wonder supporting this syntax would speed things up a little bit.
Here's a simple benchmark about the situation we are discussing here:
There are 2 tables:

My guess is that the latter will perform better but you should do your
own testing.

and how would I use DISTINCT ON for this query? Please bear in mind,
that there is more then one id_bf (just stopped the sample data with
one of them)
I posted the answer more than hour ago:
SELECT DISTINCT ON (id_rf) * FROM rfmitzeit ORDER BY id_rf,
letztespeicherung DESC;
The equivalent
You could try to prepare a query like this:
select name from foo where id=any($1);
and then pass the array of integers as $1 (although, I don't know how
you can do that as I've never used the C interface of libpq).

How about using replication instead of incremental backups?

I have the following definitions:
--
create type mytype as (x integer, y integer);
create table foo(
a mytype primary key,
b integer
);
create table bar(
a mytype references foo
);
insert into foo values((0,0)::mytype,0);
In 8.4, the sequence value is copied only when INCLUDING DEFAULTS is
specified. Otherwise, only the not null constraint is copied. I think
this is the most reasonable behavior and I don't see why it should
have been explicitly stated in the manual.

Suppose that you have a query, say $sql_query, which is very
complicated and produces many rows. Which of the following is going to
be faser:
$sql_query OFFSET 3000 LIMIT 12;
or
BEGIN;
DECLARE cur1 CURSOR FOR $sql_query;
MOVE 3000 IN cur1;
FETCH 12 FROM cur1;
COMMIT;
