Hi!

I must be blind or something but it seems I just can't
figure out a working procedure to restore a PG dump in
custom format (created with "pg_dump -Fc") into several
different PG databases with different owners (i.e. for
testing purposes)

I want to do something like that:

On database server A:
pg_dump -Fc testdb_orig > testdb_orig.dump

On database server B:
createuser abc
createuser def
createuser xyz
createdb -O abc abc_db
createdb -O def def_db
createdb -O xyz xyz_db
pg_restore -d abc_db -O abc testdb_orig.dump
pg_restore -d def_db -O def testdb_orig.dump
pg_restore -d xyz_db -O xyz testdb_orig.dump

(this simple example above won't work as pg_restore option
"-O" doesn't accept the name of the new owner as parameter)

Depending on the combination of options (like "-U" or "-O")
I give to pg_restore, I either get errors or I end up with a
database owned by the original owner of the dumped database
or the database superuser (which I do not want)

Is there really no way to tell pg_restore to set the new
database object's owner to a DB user which already exists?

I really don't want to manually set ownership of hundreds of
database objects like tables, functions, domains, sequences, ...

Please tell me I just overlooked the obvious... ;-)
