Basically yes.
Cluster contains also  small test database which actually does not need 
transferred but I can delete it manually after transfer.
Also postgres, template0 and template1 are not used directly by applications 
and probably does not need to be transferred.

Source cluster is in old Debian 6 Squeeze running Postgres 9.1
Should I create pipe using pg_dumpall and restore everything from old using 
pipe instead of pg_dump/pg_restore ?
