There is only one way - implementation of CALL statement. Any
emulation on JDBC level is just way to hell. Now, we have to say -
PostgreSQL doesn't support a CALL statement, support only functions -
and everybody has to use a different pattern than in other databases.
Any emulation on JDBC means, it will be slowly, it will be
unpredictable.
