Fix missing values when doing ALTER TABLE ALTER COLUMN TYPE This was an oversight in commit 16828d5c. If the table is going to be rewritten, we simply clear all the missing values from all the table's attributes, since there will no longer be any rows with the attributes missing. Otherwise, we repackage the missing value in an array constructed with the new type specifications.
Backpatch to release 11.
