Small updates with something o found recent days:

```
db2=# create incremental materialized view v2 as select * from v1;
ERROR:  VIEW or MATERIALIZED VIEW is not supported on incrementally
maintainable materialized view
```
Error messaging is not true, create view v2 as select * from v1; works fine.


```
db2=# create incremental materialized view vv2 as select i,j2, i / j2
from t1 join t2 on true;
db2=# insert into t2 values(1,0);
ERROR:  division by zero
```
It is very strange to receive `division by zero` while inserting into
relation, isn't it? Can we add some hints/CONTEXT here?
Regular triggers do it:
```
db2=# insert into ttt values(100000,0);
ERROR:  division by zero
CONTEXT:  PL/pgSQL function f1() line 3 at IF
```
