Thread: restore improvement

I think the restore process could be made more error proof if the following 
additions could be made:

pg_dump, (maybe started with a special flag) if run with superuser rights 
should not issue

\connect - username
create table foo (...
copy foo from ...

to create tables, but use this syntax:
create table foo(...
copy foo from ...
update pg_class     set relowner=u.usesysid   from pg_user u where u.usename='username' and relname='foo';

This would avoid situations where a restore becomes impossible because 
password authentication is necessary. This would allow restoring  without 
having to set trust in pg_hba.conf. A patch would be simple, in fact I wrote 
it within a few minutes. 

Or am I completly wrong and there's a better way to accomplish this?

Best regards,Mario Weilguni

set session authentication 'username';

The command already exists in 7.2devel sources.  Feel free to send a patch
to make pg_dump use it.  Note that this command requires superuser rights,
so there needs to be an alternative.
