Is it possible to execute stored procedures?

[StanislavIsaev]

I'm in the middle of POC to use ShshardingSpherearding-Proxy in our company.

But can't find a way to execute stored procedures.

The client uses Postgres jdbc driver, the Proxy frontend is also Postgres, the backend is Oracle.
Trying to execute conn.prepareCall leads to an exception.

Trying to use ShshardingSpherearding-Jdbc just to see what will happen and see that ShardingSphereConnection doesn't support this:

@Override
    public final CallableStatement prepareCall(final String sql) throws SQLException {
        throw new SQLFeatureNotSupportedException("prepareCall");
    }

Is there some workaround on this or plans to support Callable Statements?
