uff. How you would to write scripts? How you would to join client side
and server side? What I know, statements in PostgreSQL are
parametrised - INSERT, SELECT and others.

DO should have any syntax. Other than I wrote. It isn't important in
this moment. Do without parametrsation has not full power. It is like
EXECUTE without USING clause. Sure. You can live without it, but the
live with it is much more confortable. So now we have isolated PL
fragment without any outer inputs.
