My first challange with restoring from dumps across different versions...

in pgsql 7.4.2:
I use pg_dumpall > $BACK_DIR/pgdumpall_test$TSTAMP.dmp.
I than copy the dump file over to another machine with pgsql 7.2.2.
I want to pg_restore just one database (i.e. wxsdb) without having to
manually clear data and tables, also ignore the original owner of tables.

Is it possible with opne pg_restore (pgsql 7.2.2)?
What are the 'default' values for pg_dumpall on pgsql 7.4.2 that i may have
missed?
What pg_restore flags to use on pg_restore ?

I tried this: pg_restore -O -i -c -d wxsdb --format=c (for some reason
format=p does not exist)...
...getting constrints violations
...or users doesnt exist
...I tried to manually delete all tables, but than there are many 'types'
and 'sequences' that wont go away...

Any hints and tips will b eappreciated.
