these two yes

this is my fresh
some smarty designed asserts can be used for static analyses too.
I am able to analyze plan of DML statements, and I can raise warning if expected rows is not 1 or if there are not filter over unique index
some
UPDATE ... WHERE id = 1;
ASSERT(PROCESSED_ROW_COUNT = 1);
And I can recheck in plpgsql_check, and it can enforce fast check in runtime
