Hi Worik,

I can't address the specifics of your problem but I'll give you an example
of I do it on a 7.4 db. I dunno if all options are available on your
version.

To get the backup:

pg_dump --format=c -v DBNAME > FILENAME.dump


To restore you have to create a new DB (drop the old one first if
neccessary):

createdb -T template0  [-E ENCODING] DBNAME

Note that this is template 0 and not template 1. (also, don't forget to set
your database encoding if the default isn't what you want).


Then create a contents list:

pg_restore --list DBNAME.dump > DBNAME.list

You can edit the list file to rearrange the restore order or omit items.


Finally, do the restore:

pg_restore --use-list=DBNAME.list  --dbname=DBNAME -v DBNAME.dump


This is all documented fairly well in the online documentation, you just
need to spend a bit of time going through it. As I recall, some information
is in the admin section and some is in the documentation of the client
programs (pg_dump and pg_restore are client programs iirc).

Also, consider upgrading to 7.4 to ensure you get the best support.

Good luck,
Iain
