I am confused by the above comments.
ComputePartitionAttrs only called in DefineRelation.
DefineRelation will only CREATE a table, there will be no dropped
column via DefineRelation.

"EXPR_KIND_" can change to EXPR_KIND_PARTITION_EXPRESSION
?
Other than that, it looks good to me for fixing this bug.
