Restore: check password earlier

[dizzzz]

What is the problem

When running restore of a backup file, in localmode, the database password inside the backup file set is checked very late, causing any errors to appear very late.

In my case, this error pops-up after a few hours, which is rather inconvenient.

What did you expect

Fast failure for wrong passwords, also in localmode

My RFE: please have the username/password checked at at the beginning of the backup process.
