Having a closer look at this I can see, that's the reason in fact.
I've thought that something once in the database could be restored but
obviousely pg_dump does just a plain dump and psql does certain checks.
The problem was caused the following way:

I ported a MS-SQL 7.0 database using Access and copying the tables
over the clipboard (the longer ones, well Access considers tables
greater than about 500 lines as to big for that method ;-) where done
using pgAdmin import tool). This worked so far with the above exception:
One table has two columns type "datatime" in MS SQL. They are named
CreatedAt and ChangedAt and should store just the time when the
record waas created and log the time of a change.

Now my question is: How can I implement this in PostgreSQL that this
fields are automatically filled in this sense?

Kind regards

Andreas.
