# title:        Provide name of read-only column incorrectly referenced in UPDATE ... SET xxx
# decription:   
#                  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.
#                  Checked on 4.0.0.1142: OK, 2.359s.
