Review Comment:
next cases are unclear for now : create table ... col TIME(3) and further
query : select from .. where col = TIME '12:12:12.1234' is it need to be
implicitly casted ? And on the contrary: create table ... col TIME(3) and
further : select from .. where col = TIME '12:12:12.12'. Other words - temporal
predicate with great or less precision than column is.
