Hi Shane,
Thanks for the answer.
Actually I want to distribute specific database to a lot of different
clients(different OS/Linux;Windows/, different CPU/AMD;Intel/), and I was
thinking about only copying the files instead of dump/restore(which is must
slower operation). From your answer I guess it is impossible for now :-(.
Is there a way to tell PostgreSQL not install itself with OS or/and CPU
compatibility(for the prize of loosing performance), but that way the one
can move files free from on Computer to another?

That is basically what you are doing when you transfer (unless you are 
moving the drive to a new machine) - how you do the transfer will depend 
on your needs and what hardware and software is at the source and 
destination.

If you are looking for a backup server to be ready to use as soon as 
your production server fails then you can look at PITR or 
synchronization such as slony-1

If you want to copy your database to a development machine occasionally, 
then if they have the same hardware and postgres version then you should 
be able to copy the data files across while the production server is 
stopped without problems. Some differences between CPU and postgres 
version can stop this from working.

You could also do the dump/restore directly from one machine to another 
if they are on the same network without having the dump file to transfer 
across and import which will give similar results.

eg. instead of -
pg_dumpall > mybackupfile
psql -h my.other.machine.address < mybackupfile

you can -

pg_dumpall | psql -h my.other.machine.address

If you have different cpu's (one Intel and one AMD64) or different 
postgres versions then you will have to do the dump/restore even if it 
is sent straight from one to another.

For more help specify what hardware, system and postgres version you 
have on each machine and what you wish to achieve in transferring.
