Hi once again

Am I right to assume that running a pg_dumo -Fc against a database:

(i) Does not require WAL log archiving be be switched on?
(ii) That running this will have no (or a very small) effect on the database's performance?

Also in general, are there any performance hits from runing in WAL Archiving mode and also any when a pg_start_backup is actually running

Thanks

Austen
