> Considering this condition, (a or d) and (a or c) and a and b. This condition can be simplified to a and b, but now simplify can not do this.
> This case is found out by materialized view test:
> materialized view: select 'a',\"empid\",\"deptno\",\"salary\" as s from \"emps\" where (replace(\"name\",'\\2','a') is not null or replace(\"name\",'a[[:alpha:]]{5}','c') is not null) and (replace(\"name\",'[[:blank:]][[:alnum:]]*','b') is not null or replace(\"name\",'(.*)(.)$','d') is not null)
> query: select \"salary\" +1 as s,\"deptno\" from \"emps\" where
>             replace(\"name\",'[[:blank:]][[:alnum:]]*','b' ) is not null and replace(\"name\",'a[[:alpha:]]{5}','c') is not null and \"salary\">10
