RE: [GENERAL] About triggers

Trigger functions must return opaque.  Try

    CREATE FUNCTION testf()
      RETURNS opaque
      AS
      'INSERT INTO TEST VALUES(\'Hi\');
       ...
       ...
       return new;'
      LANGUAGE 'sql';

    I do the following :


    CREATE FUNCTION testf()
      RETURNS bool
      AS
      'INSERT INTO TEST VALUES(\'Hi\');
       ...
       ...
       SELECT true;'
      LANGUAGE 'sql';

    then :

    CREATE TRIGGER syn_section_insert
      AFTER INSERT ON SECTION FOR EACH ROW
      EXECUTE PROCEDURE testf();

    ... and I obtain

    ERROR:  CreateTrigger: function testf () does not exist

    but function exists...

    What's the problem?

    TIA.

         Roberto
