I looked to some documentation - and for example - the PL/SQL PRAGMA inline
looks very similar to what I propose.

For me good enough is block level pragma used in DECLARE section

DECLARE
pragma plpgsql_check(OFF);
BEGIN
.. this part will not be checked ..
END;

The syntax will be prepared for future PL/SQL pragmas like
AUTONOMOUS_TRANSACTION, ..
