hello tom ..
.. i am sorry for not replying any earlier
.. i was taken up by our project, which is now finished
(that much work for a 1 week congress)
.. today i took the time to get the top of the 7.3 branch
and recompiled everything ..
.. i can now confirm the top of the 7.3 branch does fix my problem

while i am at it(i finally have enough time to write elaborate emails)
i ran into some problems while playing with 7.4beta2(from cvs)

i am not able to reload my database after dumping it
.. as fas as i realized that _is_ mandatory for upgrading to 7.4 .. isn't it ?

this problems _is not_ 7.4 specific
.. saving and restoring doesnt even work painless for version 7.3.4

several problems:
* schema definitions are not restored correctly
CREATE SCHEMA AUTHORIZATION person;
will be dumped as:
SET SESSION AUTHORIZATION 'person';
CREATE SCHEMA 'person';
which of course will not work
because person will not have the right to create schemas
* functions are not dumped in the right order
example:
FUNCTION lecture_bookings_intersection_p
requires
FUNCTION lecture_bookings_intersection
but is scheduled to be restored before it
most of the ERRORS in the log are generated by a cascade
(function doesn't get created -> table doesn't -> view doesnt -> access can not be restored)
* views that are in different schemas
but have certain access restrictions
do not get created because of privileges
(VIEW mafing in SCHEMA strauss for example)
[couldn't identify the source of that problem]

if you have any pointer
* something that i could improve in my database design
* some options i forgot to specify on pg_dumps commandline
* a different place where i should ask my question
* some patches that i could try for you

thank you very much in advance

PS: i put all the files in the download directory of our project-server
(please append .gz to get smaller gzipped files)

http://dmv.math.uni-rostock.de/downloads/global.sql -> users definition

http://dmv.math.uni-rostock.de/downloads/database.orig.sql -> original database dump
http://dmv.math.uni-rostock.de/downloads/database.new.sql -> edited databasedump with CREATE SCHEMA AUTHORIZATION
http://dmv.math.uni-rostock.de/downloads/database.orig-new.diff -> the diff between above files

http://dmv.math.uni-rostock.de/downloads/error.new.log -> the original error log
http://dmv.math.uni-rostock.de/downloads/error.orig.log -> the smaller one after the change mentioned above
