Since custom types are hashable in PG14 the partition test will be
different on PG14. Since the only difference was testing whether
creating hypertable with custom type paritition throws errors
without partitioning function that specific test got moved to ddl
tests which already is pg version specific.
The index creation code would take the IndexInfo from the hypertable
and adjust it for the chunk but wouldnt reset IndexInfo for each
individual chunk leading to errors when the hypertable has dropped
columns.
Fixes#2504
