Also, what tests can we add for backup/restore? We have nothing at all at the moment, and it is pretty troublesome. I'd like to ensure that we can backup and restore a database correctly, and ensure that the displayed commands are what we expect and that we get valid output from pg_dump/pg_restore (though, it may change from PG version to PG version, so maybe we should just check for something small and generic). I guess this might need some config parameters for the tests to specify the pg_* utility paths for each server.
I'd suggest maybe having a feature test that opens the prefs, sets the appropriate path, then runs a backup, waits for it to finish, checks the process monitor output, then restores the same backup to a new database, checking the process monitor output again, and then checking that the restored database contains at least one object from the original database (we don't need to check all of pg_dump/pg_restore, just that something expected was restored). We should use a (partial) database name and backup filename from the advanced test config file, and I think both should default to some interesting non-ASCII strings to ensure quoting works.
