A pg_dumpall script expects to be restored into an empty cluster.

The -c flag should cause the script to DROP all your databases first. But that switch has been known to have bugs in the past, and in any case it could fail if there are other sessions connected to those databases. Did you pay attention to whether the restore reported any errors?
