pg_dump and restore

Hello,

Im really struck with trouble when I first tried to copy a database
to another host. I followed the dos and did:

host1 ~> pg_dump <database> > dump
host2 ~> cat dump | psql <database>

Now I tried to check wether all went right and did

host2 ~> pg_dump <database> > dump2

So dump and dump2 shouldn't differ (at least not in importantly) I think.
But there is a great difference between the database. About half of the
table is missing. To make sure I tried

host1 ~> cat dump | psql <database2>
host1 ~> pg_dump <database2> > dump2

to verify if this problem also remains if I'm sitting on the same
database server. And so it was :-((.

How could that happen????

I append the output while the psql-insertion to this mail. May be it
gives some hints for those not as new to PostgreSQL as I.

I'm using PostgreSQL 7.0.2 on a Debian GNU/Linux system.

Kind regards

Andreas.
