Migration problems from source 9.3 to omnibus 9.3

When i transfer schema i get the following error:
sudo -u gitlab-psql pgloader /tmp/commands.load

when trying to recover the data from the backup I get the following error:

Before restoring the database we recommend removing all existing
tables to avoid future upgrade problems. Be aware that if you have
custom tables in the GitLab database these tables and all data will be
removed.
