@DonnyZone @gatorsmile @cloud-fan PostgreSQL will throw an error when
comparing a string to a int.
```
postgres=# select * from tb;
a | b
------+---
0.1 | 1
a | 1
true | 1
(3 rows)
postgres=# select * from tb where a>0;
ERROR: operator does not exist: character varying > integer
LINE 1: select * from tb where a>0;
^
HINT: No operator matches the given name and argument type(s). You might
need to add explicit type casts.
