I think it would be OK that if you want to move a hash-partitioned table to a database with a different encoding, you have to do dump/restore through the parent table. This is quite similar to what you have to do now if you want to move a range-partitioned table to a database with a different locale. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
