Peter Eisentraut 7ac030d5b1 Require UPDATE permission on FOR PORTION OF column 
It seems like the SQL standard does require this after all, and it
makes sense because these columns get changed.  (This is not to be
confused with *not* requiring INSERT permission to add the temporal
leftovers.)

Adding the column to RTEPermissionInfo->updatedCols also fixes a
couple outstanding bugs from other (non-permission) features using
that bitmapset to detect changes: GENERATED columns and UPDATE OF
triggers.  This patch includes test cases to exercise those scenarios,
including on partitioned tables.
