Don't test for connections before the restore
Don't test for connections before the restore

The first part of the restore is to drop the database. This will fail
if there are connections to the database.

Failing before we call restore will also prevent us from fixing
the situation by removing any pglogical subscriptions that may
be present before dropping the database.

Instead we can print an error after we fail to inform the user
that the failure was because there were connections to the database.
