commit 39ef2bdd10be535e2d588bfd9ff2e2e52b936169

Revert "Ban enums as distribution and partition keys"
This reverts commit a863997e6459e907979478f013b588447385ca07.
The issues with restoring enums in distribution and partition
keys has been resolved in pg_dump by the cherry-pick of
7e7c5b683985c85fb990c4d49ab960cbc83434b4.
A gpbackup fix disables gp_enable_segment_copy_checking before
loading a table/matview with an enum hash distribution/partition,
then reorganizing the table after it's loaded and resetting
the GUC.
With these two changes it's safe to unban enums as distribution
and hash keys.
