Hello guys! I'm migrating from 0.17 to 0.20. I was using jsonb data type from here:
```<https://gist.github.com/quangIO/a623b5caa53c703e252d858f7a806919>```
 and i found out that ColumnType seems to be changed

If your problem is `setParameter` function please try:
```    override fun setParameter(stmt: PreparedStatementApi, index: Int, value: Any?) {
        val obj = PGobject()
        obj.type = "jsonb"
        obj.value = value as String
        super.setParameter(stmt, index, obj)
    }```
