After putting it into an archive with pg_dump, I got:
pg_restore: [archiver] unsupported version (1.7) in file header
on destination machine. It's not clear what 1.7 is though, cause all
pg... version involved are 7.x.y, whereas tar versions are both 1.13.25.

P.S. Going to try 2 more things on my mind.

Sincerely,
r.

I’m having a problem restoring the DB on the remote server. The best
luck I had was with 
psql dbName < filename
& 
psql myDB
\i filename

However, in both cases I'm getting the following error for all data
entering statements (all of which appear to be based on COPY ...):
psql:trial:LineNumberHere: invalid command \N

There are indeed some \N denoting NULL; however, even when there are no
NULL values in a table the statements always fail too.

So I ended up with tables, indexes, and constraints, but w/o any data,
and I don't know what to do about it. I could put together manually a
long list of SQL statements, but that's not a real solution when there
is a tool available.

P.S. pg_restore command failed with errors like:
pg_restore: [archiver] input file does not appear to be a valid archive
pg_restore: [tar archiver] could not find header for file toc.dat in tar
archive

P.S. Notes:
Source DB is 7.3 and unicode, while destination is 7.2.3 and latin1.
Could affect anything? If it could, I'd have to dig for changes in the
destination.
P.P.S. Example of a COPY statement:
COPY region (id, name) FROM stdin;
1       Mid-West
2       East Coast (N)
3       East Coast (S)
4       Southwest
5       Northwest
6       South

Thank you in advance,
r.

I’m also about to do that and also asked that a while ago (thanks to
everybody who replied then).
From help, I see suggested syntax of
1) pg_dump –f filename
I guess it does the same as 
2) pg_dump > filename

On the destination server, from help I’m seeing syntax like
1) pg_restore –d myDB filename
(to my guess).
That is different from 
2) psql dbName < filename
but the result will probably be the same.
Then there is also:
3) psql myDB
\i filename

Is there any difference b/n the 2 dump and the 3 restore ways? If yes.
which of the 2 and 3 ways are preferable? 
Thanks,
r.

I would suggest doing a 
 
pg_dump > filename
 
then save that to disk, email it, ftp, whatever to the destination
server, and
 
createdb databaseName
psql databaseName < filename
