ISSUE:       6133
TITLE:       Provide name of read-only column incorrectly referenced in UPDATE ... SET xxx
DESCRIPTION:
  Table with computed field (non-ascii) that is result of addition is used here.
  UPDATE statement is used in trivial form, then as 'update or insert' and as 'merge'.
  All cases should produce STDERR with specifying table name and R/O column after dot.
