SQL/PSM is better. This language is developed to integration to SQL.
It allows one statement procedures. So

IF .. THEN ELSE END IF; isn't correct code for PL/pgSQL and it is
correct for SQL/PSM.

so
FOR r AS SELECT * FROM information_schema.tables
DO GRANT .... ON r.table_name TO ...;
END FOR;

sql/psm doesn't need DECLARE, BEGIN and END in this case;
