Schema.quoteColumnName() quoting problem

[abolotin]

Hello

I have PG database with schema/table/column names containing upper cased symbols. I want to add condition, for example:

app."Applications"."Status" = ...

Using query builder in search model:

$query->andFilterWhere([
self::tableName() '.{{%Status}}' => $this->Status
]);

But resulting SQL contains condition: WHERE "Status"=...
This causes an error, because of SQL contains joins with another tables, whic also have own "Status" columns.

self::tableName() returns value: app.{{%Applications}}
As i understand, problem in yii\db\Schema, quoteColumnName($name) function. Code:

    if (strpos($name, '{{') !== false) {
        return $name;
    }

should be replaced with:

    if (strpos($name, '{{') !== false) {
        return $prefix . $name;
    }

???
